Question

If x= a(sin theta+ cos theta)
Y= b(sin theta - cos theta). ,represents,
A)PARABOLA B)HYPERBOLA C)ELLIPSE D)CIRCLE

Answer 1

Answer:

X/a=sintheta + costheta

y/b=sin(theta)-cos(theta)

(x/a)²+(y/b)²=(sintheta +costheta)² + ( sintheta- costheta)²

sin²theta + cos²theta +2sintheta*costheta +sin²theta + cos²theta -2sintheta*costheta

2(sin²theta + cos²theta)

2*1=2
