Eliminate `theta` from
`a sin theta + bcos theta = x "and" a cos theta -b sin theta = y`

x = a cos theta, y = b sin theta .

Eliminate theta : x=2 sin theta, y=3 cos theta.

Eliminate theta : x = a ( cos theta + cos 2 theta), y = b ( sin theta + sin 2 theta).

Eliminate theta from the equation , a=x sin theta-y cos theta and b= x cos theta + y sin theta .

Eliminate theta,if x=a cos^3 theta y=b sin^3 theta

Eliminate theta from the equation s=sin theta +"cosec" theta and r= sin theta-"cosec" theta .

Find the relation obtained by eliminating theta from the equations x=a cos theta+b sin theta and y=a sin theta- b sin theta .

The eliminant of theta from x cos theta - y sin theta = 2 , x sin theta + y cos theta = 4 will give

Eliminate theta from lambda cos 2theta = cos(theta + alpha) and lambda sin 2theta = 2sin(theta + alpha)

Eliminate theta from lambda cos 2theta = cos(theta + alpha) and lambda sin 2theta = 2sin(theta + alpha)
