A man weighing 600N steps on a scale that contains a spring. The spring is compressed 1cm under their weight. Find the force constant of the spring and total work done on its compression.

relevant equations: F = k*x      F is force, k is spring constant and x is displacement from equillibrium.

W = 1/2kx2      W is work done.

rearranging F = k*x and using t...

Differentiate y = (sin(x))^2 (find dy/dx)

This a relatively simple question which requires the use of the chain rule to solve. First we set u = sin(x)  so we then have y = u. Next we perform do differentiations, one on u as a functio...
