Help with calculus problems needed? - Yahoo! Answers
I could use some advice im just looking for hints as to how to attack these problems... It's the beginning of Calc 2 and i didnt get the background i should have due to taking 1 in highschool with a not so great teacher.
Thank you

thanks alot tho...
how about the algebraic form of tan (arc cos x/2)
i drew the right triangle x is on the adjacent side 2 is on the hypotenuse then you take the arc cos rule of u prime over square root of u^2 - 1
