How Do You Use an Engineering Calculator?

Blog online engineering calculator Also called a “scientific calculator,” an engineering calculator has a series of built-in trigonometry functions, which are used in a variety of science and math disciplines. You might know all the math and science formulas. But if you don’t know how to use this kind of calculator, you’ll never get the right answer. your first need to know how calculators differ from one another. There are three main types of calculators: basic, business, and scientific. You can even find a construction calculator with functions that are specific to this profession, but each one will have a set of functions that cater to a specific type of user.

You don’t want to perform engineering or scientific calculations on a basic or business calculator, because they don’t have the necessary functions to do trigonometry and other mathematical operations. An engineering calculator can do exponents, logarithms, and a variety of other trigonometry functions. And these functions are important if you’re working with scientific notations or any type of geometry component. Basic calculators can add, subtract, multiply, and divide; while business calculators have buttons for calculating interest rates and other functions. But they tend to ignore the order of operations.

Functions of an Engineering Calculator

The labeling on each button will vary between manufacturers, but there are some common functions that are on every engineering or scientific calculator. In addition to the standard arithmetic operations (which are included in every calculator), there are functions that can help you to calculate any of the following:
  • Exponents
  • Square roots
  • Natural logarithms
  • Sines
  • Cosines
  • Tangents
  • Inverse tangents
There are also functions that will allow you to store numbers for later use, which can come in handy if you’re performing complex operations.

Using an Engineering Calculator

The most obvious way to learn how to use a calculator is to read the manual. But if it didn’t come with one, you should be able to search for the model number online so you can download an electronic copy. If you don’t read the manual, you’ll either have to do some experimenting or enter the right numbers only to get the wrong answer. This is because different calculators process the order of operations differently. You need to know which keys to press and when to press them. If you want to calculate the square root of a number, you should find out if you need to enter the number before the square root key or if it’s the other way around. If you’re working with angles, you need to know if the answer is expressed in degrees or radians. You also need to find out if you need to enter the angle before you press cos, sin, tan, etc. You might be able to switch from degrees to radians by pressing the MODE key on the calculator, and there’s usually an indicator written along with the number to let you know what you’re getting. If you’re looking for a scientific, engineering, or construction calculator, be sure to look at what we have at Engineering Supply. We’re sure you’ll be able to find the right tool for your specific needs.
