This online scientific calculator has a full list of functions that can help you find the solution for any basic or complex math and scientific calculations in physics, engineering or any other science. Everything there is to know about the functionalities and features this web form can handle are detailed below.

## What are the functions this online scientific calculator has?

This advanced tool can assist you in solving any exercise or problems that require applying or using one of the following functions and features:

• ### Basic functions

- Addition or the so called sum function can be used by pressing “+” button between the desired variables. The simplest form to express an addition is x+y.

- Subtraction or the so called minus function can be performed by clicking “-” button between the desired variables. The simplest form to write a subtraction is x-y.

- Multiplication often referred as to times function can be run by clicking the “x” option between the desired variables. The multiplication can be easily expressed as x*y.

- Division which is also known as thedivide function can be performed by clicking the "/" button between the given variables. The division can be easily written as x/y.

- Percent available by pressing % button;

- Square can beused by clicking the "x^2" button or the desired variable and then typing "^2". The result of this operation comes from multiplying the variable by itself. For instance 5^2=5*5=25

- Cube can beused by clicking the "x^3" button or the desired variable and then typing "^3". The result of this calculation comes from multiplying the variable by itself for 3 times. For instance 5^3=5*5*5=125

- Square Root can be run by clicking square root of x button. The result displayed by this feature represents the value that if squared equals the given x value.

- Cubic Root can be run by clicking cubic root of x button. The result displayed by this function represents the value that if cubed equals the given x value.

- “y” root of “x” can be run by clicking “y” root of x button. The result displayed by this function represents the value that if it raised at “y” equals the given x value.

- Raise to a specific power written as x raised to the y can be used by pressing “x^y” button.

- Natural exponential which can be found under “e^x” button. It displays the value obtained if 2.71828 get raised to given x value.

- Natural logarithm can be used by clicking “LN” option.

- Logarithm can be used by clicking “LG” option;

- Number with exponents 10 accessible by 10^x button. Usually the result of 10 raised to given x is either too large or too small to be displayed.

- Factorial feature is available by clicking “n!” button;

- Inverse function can be found by clicking “1/x” button and is the equivalent of x^.

- PI which is a mathematical constant that represents the ratio of a circle's circumference to its diameter approximately equal to 3.14159.

• ### Trigonometric functions

- Sine often abbreviated as(SIN) represents in a right triangle the ratio of the length of the opposite side to the length of the hypotenuse.

- Inverse Sineoften abbreviated as (ASIN) or (ARCSIN).

- Cosine often abbreviated as (COS)represents in a right triangle the ratio of the length of the adjacent side to the length of the hypotenuse.

- Inverse Cosineoften abbreviated as (ACOS) or (ARCCOS).

- Tangent often abbreviated as(TAN) represents in a right triangle the ratio of the length of the opposite side to the length of the adjacent side.

- Inverse Tangent often abbreviated as(ATAN) or (ARCTAN)

## Guidelines on how to use memory functions of the online scientific calculator

Before getting into the steps on how to deal with memory functions it is mandatory to understand the functionality behind each of the memory buttons this online scientific calculator has:

• MS saves the value displayed on the screen into memory;
• M+ adds the cur­rent value dis­played on your cal­cu­la­tor to the  num­ber saved in memory;
• M- sub­tracts the cur­rent value dis­played from the num­ber in saved in memory;
• MR recalls the value saved in memory;
• MC deletes the value saved in memory.

For instance in order to test all these features you can try to the following steps:

a) Test MS and MR features:

- Type for instance 3 and then press MS, which means the value specified should not be saved into memory.

- Clear the value from the screen then input another value for instance 5 and then press MR button to see that the screen changes to 3 number which was previously saved with MS function.

b) Test MC feature:

- First use MS to save the number 4 into memory, test if it was saved by pressing MR. Then press MC to delete it and then again press MR to see that the 4 number is not displayed.

c) Test M+ and M- features:

- M+ test: first use MS to save the number 4 into memory, test if it was saved by pressing MR. Then press M+ to add 4 to the 4 saved in memory, and finally you will obtain on the screen 8.

- M- test: first use MS to save the number 4 into memory, test if it was saved by pressing MR. Then clear the screen and input 10, then press M- to subtract 4 from 10 and finally you will obtain 6 on the screen.
