Consider the function f : [􀀀-pi,pi] --> R given by f(x) = e􀀀^-x*sin(x). (a) Calculate local maxima/minima and points of in ection of f(x).

Hi, can someone confirm if i got the right answer to this question. SO the region between curves y=x^2+1, y=2x^2-2 and the two axes, Is rotated around the Y-AXIS to form a solid glass vase. Determine the volume of the vase. I got 4*pi. Need confirmation i...

simplify: cos(sin^-1(x)) Can someone please show a step by step of how to do this.

How do you get the point of inflections?

Why did you use shells?... it doesn't have a whole in it?

I think you can use pi*y^2 for y-axis too... the cyclindrical shells method however i think is only used when a hole is formed when rotating around one of the axis.
