Question

Find dy/dx and d^(2)y/dx^(2) if possible, find the slope and concavity (if possible) at the point corresponding to theta= pi/4

Answer 1

Everything can happen if possible if and only if we have some function to work out. :)

Answer 2

Read the question again. Smh.

Answer 3

I did, still not see the function :)
dy/dx and d^2y/dx^2 of what??? what is y of x??
the point corresponding to theta = pi/4, that is the point, not the function
