How I picked the best graphing calculators for engineers

One of the main reasons I came up with these compilations is because I realized that I spend half of my working hours on my calculator. I also realized that we tended to borrow these gadgets more from one another in high school and college and even at times while at work. The quality and type of calculator one had done affect the quality and amount of work one would do. Sitting for the exams was a nightmare especially when you have a calculator with limited capabilities. I have realized that the graphing calculator is part of my lifeline and one of the most treasured investments. I took the time to rally some of my friends in different fields that I know so well use complicated algorithms and math to find out what most of them found convenient. I also went down to the high school level and picked on the preferences and while working with this group came up with what would be the ultimate calculator for everyone. This meant a calculator that would be useful at every level from high school to an ideal engineering work situation.

We also put these calculators to the test both in functionality and convenience over time-solving some of the most common and some of the rarest equations there are. We were certain by the end of the day that these three calculators are ideal for a vast school and work situation, cutting across various needs and preferences. I have spent countless hours working with various calculators all the way from high school having to switch some due to capabilities, and this has also helped me to pick what works best in my engineering field. We insisted on calculates that worked with the modern times when it comes to connectivity. One of the most critical aspects of our time is the ability to share data, as well as improve on what has already been built. This meant having a calculator with some form of connectivity to peripheral devices for uploads and downloads as well as having a calculator that would evolve regarding being programmable and expanding in storage size.

Factors to consider while buying graphing calculator for engineers

Price

It is almost religious that the first thing you will consider before buying any calculator is the pricing. It is a fact that these calculators are more expensive than your day to day simple math calculators and for some reasons. These calculators are an investment for any high school, a college student and engineer that is looking to get work done fast and easy. Most will range between $50 to $200 which is majorly determined by the specs of the calculator. The higher the capabilities, the more expensive the calculator will be. Some will work up to the high school and college level, and that is it. Those that will take you all the way will cost more but will be worth every penny at the end of the day. We ensured that our three choices were both reasonably priced and full of functions that any user will find more than useful in some areas including science and math. Cheaper calculators will have a compromise at some point which may be discovered later. It is wise that you ensure your calculator has all the specs and features that you need to get the work done. Certain brands will cost more but for a reason. Going for brands that are known to make good calculators will cost slightly more but are worth the risk as compared to brands that are cheaper but without any standing.

Build

The build of a calculator, in this case, refers to the overall physical aspect. Calculators are handy tools and will often be used. The chances are that they will fall or even be exposed to rough handling depending on what one is doing. Ensure you go for calculators that are not only effective but sturdy enough to withstand different conditions. The screen also needs to be large enough for better viewing and use. Larger coloured screens not only look better but present more capabilities for the calculator. Some will even have touchscreen options which are a matter of preference. Calculators will come with different keyboards, and some will have reversible capabilities. Some will use the QWERTY system while others will not. The kind of system one is working with, and especially the college and high school students will limit the use of some keyboard setups. QWERTY is not accepted in some while it is accepted in others. Ensure that you get the right information about what you will be working on and with and what is allowed regarding calculators. Calculators with periodic table may not be allowed for chemistry and Physics papers while others will be allowed. Taking this into consideration will save you the frustration of not working with on during the test.

Test Application

Just as reiterated above, some calculators will not be allowed for certain tests. Some will also not be compatible enough to help you during tests. Some of these tests include SAT, AP and NMSQT. Taking the time to inquire more about the nature of the tests will inform you more about the calculators supporting the same. Not all calculators will work for SATs while some will do very well. Some will work for all of them but will cost more. What you pick will be dependent on the nature of the need you have. Engineers and scientists will have to find calculators with more specs as compared to a high school student. The exams and challenges they face will also be at different levels. Some calculators will easily work out linear and differential equations while others will work on none or just one. Some will work as a mechanical engineer while others will work as an electrical engineer. Some will easily handle both. Ensure that your test and application works before buying one.

Learning Capabilities

There are quite number of learning engagements that calculators will work with, including Pre-algebra, Algebra 1 & 2, Trigonometry, Geometry, Pre-calculus, Calculus, Business & Finance, College Math, Mechanical Engineering, Differential equations, Linear equations, Linear algebra, Life science, Earth Science, Physical Science, Biology, Chemistry, and Physics. Pick a calculator that will work for your course or need. Some calculators are programmable while others are not. Those that are programmable will be more advanced and are used by developers to create as opposed to finding answers from formulas. These will have computer software working in them to increase computing power. They will also have the ability to work with peripheral devices. Some of the calculators will also have internet capability allowing upload and downloads besides browsing. The level of the need will determine the kind of graphing calculator you want to work with.

Accessories

Calculators will come with some accessories that will make it easier to use. These include peripheral gadgets and even the internal ones. One of the most useful ones is the USB port and cable. This allows you to connect and transfer data. Calculators that work with intricate information will often need support from external sources and connectivity will be a good thing. Some of these accessories also include a rechargeable battery. A rechargeable battery keeps you working for longer as compared to alkaline batteries that need to be replaced every other time. They are also more convenient to use and environment-friendly. Other accessories will include Wi-Fi capability, the ability to insert images and even symbols. Accessories also determine the value of the calculator with one that is more detailed costing more.

Memory and Storage

The memory and storage capacity of the calculator determines how much information it can store as well as how fast the calculator is. Calculators with more in terms of RAM will compute faster and better especially where higher pixels are needed. Low memory will cause delays and ‘hanging’ and this will only infuriate the user. Bigger storage spaces allow you to input and keep more data in the calculator. More data will result in more work getting done which is a good thing. Some calculators will have expandable storage which is a good thing depending on the kind of work one is into. It is wise that you pick one that has this capability especially if you plan to take notes and work with a lot of images.

Why trust me and this review?

My vast knowledge in the area of mechanical engineering has taught me the value of picking the right tools for the job. It not only makes the job more effective but increases the quality too. The best calculator is bound to save you a lot of sleepless nights due to long hours of work. I have also been a student most of my life and calculators heavily determined output when it came to studying and exams. Students that compromised when it came to picking the right calculators often paid for it in the end regarding the quality of work done. I have bought countless calculators, of course, some of them useless and some good ones. I have since then realized that it is often better to invest in one useful gadget that will last you a lifetime as opposed to compromising and making do for the time being. My whole agenda is to save you money, and the time you would take buying the right calculator.
