Scientific/Engineering Calculator -- Buyer’s Guide
Looking for an engineering calculator is no walk in the park. You will want to identify some of the essential functions that you can’t do without. Most engineering calculators are scientific because they cover a wide array of engineering courses compared to other types of calculators.
Here are a few questions and pointers to lead you as you pick a new calculator for engineering.
Who should use it?
If you are taking engineering classes, you have probably come across math that is far more advanced than in high school. You will need a calculator designed for such exact needs.
First, if you want a calculator that helps you solve math step by step a scientific calculator is preferable. This is because it will allow you to show the steps you used before arriving at the answer during exams. You can only check if answers are correct with a graphing calculator which is not what teachers will be looking for in final exams.
Advantages of an Scientific/Engineering Calculator
Necessary in Scientific/Engineering Coursework
Nowadays, every Engineering Major will have to own a scientific calculator. This is because of the complicated processes that you have to undertake while solving your courses. The last thing you’d like is to get involved in long pen and pencil arithmetic as well as having to do lots of rote memorization.
Quick and Easy to Use
Instead of using graphing calculators, scientific engineering calculators are much easier to learn to use for various problems. They do not pose the complexities of numerous functions which could be confusing if you are just starting your coursework in high school or college.
They solve real problems and Complex Math Questions
Among the features, you will find on an engineering calculator are logarithmic functions, trigonometric functions, fast access to constants pi and e, exponential functions, and even complex numbers. All these functions come in handy to solve problems in engineering thus providing you an easy way to explore and learn engineering coursework.
Every student who uses a scientific calculator for the engineering classes has better chances for comprehensive understanding. This is because these calculators provide a theory behind the results. You are equipped with extensive knowledge of real-life problems and the ways to solve them.
Disadvantages of Scientific/Engineering Calculators
As much as engineering calculators have helped to speed up the learning process; many people still see it as a crutch for the lazy student. This can be true to a small degree because if you grow to rely on your calculator for advanced math, you may also tend to go to it for simple math.
Which scientific/engineering calculator is allowed to GATE and NCEES exams?
NCEES (National Council of Examiners for Engineering and Surveying) and GATE (Graduate Aptitude Test in Engineering) examiners have to protect the integrity of their exams.
GATE exams are sat online hence GATE provides an online virtual scientific calculator that is available for all students sitting that exam. It gives all students an even playing ground.
Scientific Calculator vs. Smartphone Apps
Smartphones have computational powers as much as calculators. In fact, pocket-size calculators have been replaced by smartphones. But are engineering calculators better than smartphone applications? If you are not looking to punch in numbers on a real keyboard and would rather go for a touchpad, then a smartphone calculator is your ideal choice.
But the truth is; scientific calculators are complex. Smartphone apps for engineering are never 100% at par with the real engineering calculators. This means you may never have the full functionality of an engineering calculator with a smartphone app.
Is there a difference between scientific calculators for civil engineering, mechanical engineering, electrical engineering, biochemical and chemical engineering?
The first two years of an engineering student will have many standard units among all majors. This includes courses like Calculus I, II, and III, Physics I and II, and General Chemistry. This means you will be required to use a scientific calculator to solve problems in these courses.
Even so, after choosing your major, you will still need to use your scientific calculator for advanced calculations.
Scientific Calculator vs. Regular Calculators
Regular calculators perform the basic functions of multiplication, addition, subtraction, division with a few additions for solving basic-level math.
But scientific calculators go beyond these specifications and help to solve trigonometry, exponents, logarithms, and complex numbers. They cannot, however, solve functions using graphs like graphing calculators.
Scientific Calculator vs. Online CGPA Calculator for Engineering
The Online CGPA calculator for calculating CGPA only requires entering the grade points and credit hours, and it automatically gets the results just like you would when calculating GPA. On the other hand, a scientific calculator requires that you perform step by step calculations before arriving at your CGPA points.
A scientific calculator makes all the difference for engineers. From making understanding easy to bringing accuracy in Math, these calculators are here to stay. In today’s list, we have narrowed down to the five best calculators for engineering hoping that you will find the information useful for picking your ideal engineering calculator.
Now you can get better at your coursework with these best engineering calculators.
