Did you know that scientific calculators can actually calculate trigonometry problems? And were you aware that you can enter a whole string of operations into the device and it will calculate the whole thing? Read more below about the things you can do with a scientific calculator.
Scientific calculators: what exactly are these devices?
By definition, a scientific calculator is a device designed to help you calculate operations in different fields like engineering, mathematics and science. It has more buttons than your regular calculator that lets you do your usual four basic arithmetic operations of addition, subtraction, division and multiplication.
Usage
All of those buttons allow us to work with various problems such as the following:
- Scientific numbers that have a multiplication by ten to a certain power.
- Logarithm problems with base ten and the natural base
- Trigonometry problems
- Probability problems that use the factorial function
- Pi problems
You can use your calculator device to help you solve trigonometry problems involving tangent, sine, cosine, their inverses and their hyperbolic functions. When it comes to working with trigonometric values, you can also change the calculations between radians, degrees and grads. You have access to a button for pi and Euler’s constant. Also, there are buttons that allow you to calculate exponents to the second, third, or higher powers.
When working with scientific numbers, there is the Exp button that lets you easily input scientific numbers. Usually, engineering problems make use of exponents, logs as well as scientific numbers.
All of these types of problems are often longer expressions that involve many steps to solve by hand. However, with the use of a scientific calculator you can input the whole expression, simply push the equals button, and the device will perform all the calculations you need in the right order.
Memory
For certain calculations, you might want to remember a specific calculation to use at a later time. You can add a specific calculation into the memory of the device simply by clicking the “M+” memory button. Then you can recall it later by clicking the “MR” button. You can clear the memory with the “MC” button.
Note that “M+” will actually add whatever you have on the display in the screen to whatever is already in your memory, so it is a good practice to click “MC” before adding with “M+”, that is unless you have recently started the calculator.
What can I do with a scientific calculator?
If you are wondering what can scientific calculators actually do, the answer is varied: from problems with scientific notation, formulas with a geometry component, to more complex operations. These tools can provide you with answers to square roots and powers with a simple click. Similarly, scientific calculators make light work of finding mathematical solutions for angles in simple formats of degrees or radians. They support calculations required by students and specialists in trigonometry, chemistry, statistics, physics as well as other math-intensive fields.
What is the difference between scientific calculators and graphing calculators?
Graphing calculators solve complex functions as well, however they can also provide a visual display that helps professionals and students understand mathematical concepts more easily and clearly. Unlike scientific calculators, graphing devices help solve integral calculus, matrices as well as other advanced mathematical problems. These devices have larger screens to accommodate those graphics displays. They come with Wi-Fi capabilities to integrate data from other tools such as light meters, decibel meters as well as electronic thermometers; scientific calculators do not offer this compatibility. Graphing calculators are considerably pricier than scientific calculators due to those sophisticated functions.
Which calculator is ideal for me?
Before picking a graphing or scientific calculator, review your class or job calculation requirements. Make sure you ask which type is suitable for the classroom. Scientific calculators are typically adequate for student needs, in fact graphing calculators are often not allowed in school settings.
In brief…
A scientific calculator is a sophisticated version of the regular hand-held calculator or computer application that you often use. It typically includes trigonometric functions like cosine and sine, exponential functions such as square root as well as other mathematical functions. Some scientific calculators may even include graphic as well as problem-solving capabilities.
