" 18.Eliminate ' "theta'" from "x=a sec theta,y=b tan theta" ."

Eliminate theta from x=1+tan theta, and y=2+cot theta

Eliminate theta: 5x=3 sec theta, y=3 tan theta.

Find dy/dx , if x and y are connected parametrically by the equations (without eliminating the parameter). x = a sec theta, y = b tan theta .

Eliminate theta from the relations a sec theta=1-b tan theta,a^(2)sec^(2)theta=5+b^(2)tan^(2)theta

Eliminate theta from the equations a sec theta+b tan theta+c=0 and p sec theta+q tan theta+r=0

Eliminate theta from the following: x=3sec theta , y=4tan theta

Eliminate theta from the equations a sec theta - c tan theta = b and b sec theta + d tan theta = c.

x =a tan theta ,y =b sec theta

If theta is eliminated from the equations a sec theta-x tan theta=y" and "b sec theta+y tan theta=x (a and b are constants), then :
