Question

Match cach polar equation below to the best description. Possible answers are C,E,H,L,P,R,S,V, and Z. DESCRIPTIONS C. Circle centered at origin, E. Ellipse, H. Hyperbola, L. Line neither vertical nor horizontal, P. Parabola, R. Circle not centered at origin, S. Spiral, V. Vertical Line, Z. Horizontal Line POLAR EQUATIONS C 1,r= 1/18 cos theta E 2.r= 18 sin theta H 3. r = 34/4 sin theta +18 cos theta L 4.r2 = 34/sin 2 theta (Hint: sin 2 theta = 2 sin theta cos theta) R 5.r = -4 Note: You can earn partial credit on this problem.

Explanation / Answer

x= r cos heta

y= r sin heta

calculate both and eliminate theta

u will get all the equations. :)
