    Graph the learning curve L(x) = (x - 2)^3 +8

    having trouble getting started on this problem. I don't really know what to do first. A learning curve is a function L(x) that gives the amount of time that a person requires to learn "X" pieces of information. Many learning curves take the form L(x) = (x-a)^n + b (for x>0 or x=0), where "a"...

    Having a hard time with a derivative

    Can not seem to find the answer. If x^sin y= y^cos x Find dx/dy (pi/4 , pi/4). If someone could help it would be great.
