I just wanted to ask if anyone here knows how to program using c++?

If you do I need help with programing the taylor series for a cosine function with a tolerance approximation.
C++ is a very complex style/type of programming. ive been trying to learn it too, but i suggest finding some kind of C++ forum, and askin questions there. it helped me a lot...
I'm a C++ programmer, sure, but I'm not a mathemetician. I don't know anything about a Taylor series.

In general, when solving a programming problem, it's a good idea to see if it's already been solved. The question and answer provided here, for example, seems relevant.

I'm closing this topic cause I have already completed this assignment project. It wasn't easy but I was able to get my code to work.
