# Roots, Logarithms & Trigonometry

### Square & Cubed Root

 Function Name Behaviour sqrt() Square Root Returns the square root of a number (also √) cbrt() Cube Root Returns the cube root of a number
sqrt(16) | 4
cbrt(343) | 7
square root of 81 | 9
cube root of 27 | 3

### Nth root

root 5 of 100 | 2.5118864315

### Logarithms

 Function Name Behaviour exp() Exponential Calculates the value of e to the power of x, where e is the base of the natural logarithm. exp(1) returns Euler's number. ln() Natural logarithm The natural logarithm of a number is its logarithm to the base of the mathematical constant e. log2() Base 2 logarithm Calculate the base 2 logarithm of a value log(), log10() Base 10 logarithm Calculate the base 10 logarithm of a value

### Log to any base

log 20 base 4 | 2.1609640474
You can also use more natural phrases for this operation:
81 is 9 to what power | 2
27 is 3 to the what | 3

### Trigonometry functions

 Function Name sin() Calculate the sine of a value sinh() Calculate the hyperbolic sine of a value asinh() Calculate the hyperbolic arcsine of a value cos() Calculate the cosine of a value cosh() Calculate the hyperbolic cosine of a acosh() Calculate the hyperbolic arccos of a value tan() Calculate the tangent of a value tanh() Calculate the hyperbolic tangent of a value atanh() Calculate the hyperbolic arctangent of a value
Trigonometric functions assume a value in radians by default.
If you want to use degrees, specify this in the parameter:
sin(90 degrees) = 1.0
sin(90) = 0.8939966636

### Inverse trigonometry functions

 Function Name asin() Calculate the inverse sine of a value acos() Calculate the inverse cosine of a value atan() Calculate the inverse tangent of a value
Inverse trigonometric functions return a value in radians. If you want to use degrees, specify this in the parameter:
asin(0.5 degrees) = 30º
