## C Math Functions

Various mathematical functions are defines in the math.h header. All mathematical functions in this library return double as a result and take double as an argument.

### Math Library Functions

In math.h header Following are the functions defined -:

Function Description
acos() It returns the arc cosine of x in radians.
asin() It returns the arc sine of x in radians.
atan() It returns the arc tangent of x in radians.
atan2() It returns the arc tangent in radians of y/x.
cos() It returns the cosine of a radian angle x.
cosh() It returns the hyperbolic cosine of x.
sin() It returns the sine of a radian angle x.
sinh() It returns the hyperbolic sine of x.
tanh() It returns the hyperbolic tangent of x.
exp() It returns the value of e raised to the xth power.
frexp() It returns the value is x = mantissa * 2 ^ exponent.
ldexp() It returns x multiplied by 2 raised to the power of exponent.
log() It returns the natural logarithm (base-e logarithm) of x.
log10() It returns the common logarithm (base-10 logarithm) of x.
modf() It returns the value of the fraction component and sets integer to the integer component.
pow() It returns x raised to the power of y.
sqrt() It returns the square root of x.
ceil() It returns the smallest integer value greater than or equal to x.
fabs() It returns the absolute value of x.
floor() It returns the largest integer value less than or equal to x.
fmod() It returns the remainder of x divided by y.
