Raise base to the power of exp.

Parameters

base	Base number
exp	Exponent

Returns

double base ** exp

sin()

double sin

(

double

rads

)

Parameters

rads

radians

Returns

double sine of radians

sqrt()

double sqrt

(

double

x

)

Parameters

x	the number whose square root is to be calculated

Returns

double calculated square root of x

tan()

double tan

(

double

rads

)
