Question

C++ library Math.h: how to find a function in the source code?

I have a task-to parse the sin cos functions in the math library. When I opened the sources, I was hoping to see just two functions there that I would need to describe. But, instead, I found only a few lines that didn't really tell me anything. In general, are these functions in a readable form and how to get to them?

They won't be there. These are library functions. In this case, it is better to compile and see what is there.

In the case of linusk, the sine will most likely be in glibs. And the sources can be view.

In the case of various embedded systems, there may be just a nameplate.

view the implementation in freebsd.
But the processor itself can calculate with the command fcos.
