The problem statement, all variables and given/known data it's been a long summer and i forgot everything. i need help integrating 1-cos(t)dt evaluate g(x) = [[tex]\pi[/tex],x]integral (1-cos(t))dt i know by pt2 of fund. thm of calc that g' (x) = 1-cos(x) but i can't remember how to evaluate the integral and then differentiate to prove my answer.\ I should just know the integral of 1-cosx but i'm retarded and forgot what to do. any help?
