Find the arc length function for the curve y = 2x^3/2 with starting point P0(36, 432).

Find the area enclosed by the curve x = t^2 – 2t , y=sqrt(t), and the y-axis.

this is an area and arc length in polar coordinates problem. What do i do with the 4? angles where sin = 0 are at 0 and...

Need to use integrationthank you
