" If "y=sec^(2)theta+cos^(2)theta,theta!=0" then "y" has value "<=2

if y=cos^(2)theta+sec^(2)theta then

If y = sec^2 theta+ cos^2 theta, theta ne 0 , then :

If y=sec^2theta+cos^2theta,\ theta!=0, then- a. y=0 b. ylt=2 c. ygeq-2 d. y > 2.

If y=sec^2theta+cos^2theta,\ theta!=0, then- y=0 b. ylt=2 c. ygeq-2 d. y > 2.

If sec^(2)theta+tan^(2)theta=2,0^(@)

If y=cos^(2) theta + sec^(2) theta , theta != n pi, n in Z then

If x=sec theta-cos theta and y=sec^(3)theta-cos^(3)theta then the value of ((dy)/(dx))^(2) at x=0

If x = sec theta - cos theta and y = sec^(n) theta - cos^(n) theta then ((dy)/(dx))^2 is equal to

If x sin^(3)theta+y cos^(3)theta=sin theta cos theta and x sin theta=y cos theta Find the value of x^(2)+y^(2)
