Show by induction that sum_n(r3^(r-1))=1/4+(3^n/4)(2n-1) for n>0

I know how to integrate, but I still never see any real world example of it, so it is difficult to understand. Why is it useful?

What is the 'chain rule'?

curve C with parametric equations x = 4 tan(t), y=53^(1/2)sin(2t). Point P lies on C with coordinates (4*3^(1/2), 15/2). Find the exact value of dy/dx at the point P.
