Help!! I have a few questions that I need help with. 1. How do I find dy/dx of a point that I found in a previous problem? 2. Given a function f(x)=(2*x-1)*sin(pi x/2): a. How do I find the value of f ' (3)? b. How do I find the point on the graph of the function that has an x coordinate of 3. c. How do I find an equation for the line tangent to the graph at the point found in part b? I'm stuck and need some assistance, please. Gino

How do I graph the first 30 minutes of this problem? T = 32+127*exp(-.3456*30) Also, when this is graphed, it is supposed to show a horizontal asymptote.
