Question

if x=asectheta ,y=atantheta then eliminate theta​

Answer 1

Answer:

x^2-y^2=a^2

Step-by-step explanation:

x=asec theta

y=atan theta

x^2=a^2sec^2 theta

y^2=a^2tan^2 theta

x^2-y^2=a^2sec^2 theta-a^2tan^2 theta

x^2-y^2=a^2(sec^2 theta-tan^2 theta)

x^2-y^2=a^2    [sec^2 theta-tan^2 theta=1 ]
