Hi,

In a problem i have to find the angle between two curves that are in parametric form. Those curves are:

(e^t*cos(t),e^t*sin(t))and(R*cos(s),R*sin(s))where s,t are in [0,2*Pi] and R>0

I can't even find their intersection point. I tried something but i had to exclude two values of s and t which are Pi/2 and 3*Pi/2 so i could obtain s=t

Thank you in advance!
