Homework Statement
Given:
w=9(cos([tex]\theta[/tex])+sin([tex]\theta[/tex])) and u=r*w.
1) Is u continuously differentiable?
2)Is it possible to get u continuously differentiable with a different w?
Homework Equations
The Attempt at a Solution
1) u is continuously differentiable since w is in terms of sines and cosines which are continuously differentiable functions. (Is that right?)
2) I'm stuck on this one.
Thank you
