# Thread: Can someone explain what the EXP(X) function means?

1. ## Can someone explain what the EXP(X) function means?

My college professor gave us a math program assignment which gives you three options 1) Calculate X to the power of N 2) Calculate the factorial of N and 3) Calculate EXP(X) using the predefined function exp in C++

I have figured out the functions for the first two but am having trouble with the third. Our Book, Problem Solving with C++, however does not seem to go into detail about it. It just covers that EXP means e to the power of an x term. Could someone explain this better for me and give a general idea of what a function for this would be? Thanks

2. He is probably talking about raising e to a power as in 2.72?????? etc

3. i don't know what sort of course this is that you're doing, but you'll be needing e^x when you deal with logs and calculus, where x = loge(y), and y=e^x. Also, you might know some calculus, where the integral of 1/x is loge(x) + c. This course is obviously leading somewhere, such as applications of calculus with technology.
