I still, didn`t understand that kind of c++ mathematical function

can you give me a c++ program that have simple example, please?
I want to know where we use that functions

[keskiverto]

Each of those pages has an example program, doesn't it?

Even though you are new student, you probably have heard about mathematics? Trigonometry? Logarithms? Despite popular belief in schools, mathematics can actually used for something, and then one usually ends up needing some of those functions.
