1. The problem statement, all variables and given/known data Graph the curve with the parametric equations x=√(1-0.25cos^2(10t)) * cost y=√(1-0.25cos^2(10t)) * sint z=0.5cos10t explain the appearance of the graph by showing that it lies on a sphere 2. Relevant equations 3. The attempt at a solution could anyone please just point me in the right direction on how to start this problem? any help would be greatly appreciated! thanks pf!
