Mathematical Library Functions:

All of the higher level languages have rich libraries which contain many of the functions used in calculus. Examples of those can be found in your book.

In particular we list the following:

· the exponential function exp (x) for e^x

· the power function pow( x, n ) for xⁿ

· the trigonometric functions: sin(x), cos(x), tan(x), asin(x), …..NOTE: You must use radians not degrees

· The absolute value function for integer arguments: abs ( number )

· The absolute value function for float or double arguments: fabs ( decimal_number )

· The square root function sqrt(x) , same result as pow( x, 0.5)

· The logarithmic function log( x ) for natural logarithm

· The logarithmic function log10( x ) for logarithm of base 10

All of these functions are included by the <math.h> header

We also suggest that you check the help section of your software. For example in Visual C++ from HELP – Index we can find the following:

And if we select math routines and we click display we obtain a list of the functions. Clicking on a function generates a full explanation for that particular function. For example:
