# Scientific Calculator

This is a very powerful Scientific Calculator
You can use it like a normal calculator, or you can type formulas like (3+7^2)*2
It has many functions you can type in (see below)

## Examples

• Type in 12+2*3 (=18)
• Select "deg", type in cos(45) (=0.7071067811865476)
• Type in 2/sqrt(2) (=1.414213562373095)

## Function Reference

A function will return NaN (Not a Number) when you give it invalid entries, such as sqrt(-1)

### Operators

+ Addition operator Subtraction operator Multiplication operator Division operator Power/Exponent/Index operator Parentheses

### Functions

sqrt Square Root of a value or expression. sine of a value or expression cosine of a value or expression tangent of a value or expression inverse sine (arcsine) of a value or expression inverse cosine (arccos) of a value or expression inverse tangent (arctangent) of a value or expression Hyperbolic inverse sine (arcsine) of a value or expression Hyperbolic inverse cosine (arccos) of a value or expression Hyperbolic inverse tangent (arctangent) of a value or expression e (the Euler Constant) raised to the power of a value or expression The natural logarithm of a value or expression The base-10 logarithm of a value or expression Absolute value (distance from zero) of a value or expression convert radians to degrees convert degrees to radians −1 for values less than 0, otherwise 1 round to nearest integer Returns the largest (closest to positive infinity) value that is not greater than the argument and is equal to a mathematical integer. Returns the smallest (closest to negative infinity) value that is not less than the argument and is equal to a mathematical integer. factorial function

### Constants

pi The constant π (3.141592654...) Euler's Number (2.71828...), the base for the natural logarithm
