What is the value of (tan^(2)theta-sec^(2)theta)/(cot^(2)theta-cos ec^(2)theta)?

If theta is a positive acute angle such that sec theta=cos ec60o, find the value of 2cos^(2)theta-1

cot^(4)theta+cot^(2)theta=cos ec^(4)theta-cos ec^(2)theta

tan theta+cot theta=20 then sec^(2)theta xx cos ec^(2)theta

If theta is an acute angle and tan theta=(1)/(sqrt(7)), then the value of (cos ec^(2)theta-sec^(2)theta)/(cos ec^(2)theta+sec^(2)theta) is 3/4b.1/2 c.2d.5/4

find the value of (cos ec^(2)theta-1)tan^(2)theta

Minimum value of sec^(2)theta+4cos ec^(2)theta is

Minimum value of sec^(2)theta+4cos ec^(2)theta is

If sin theta+cos ec theta=2, then the value of sin^(8)theta+cos ec^(8)theta is

(cos ec^(2)theta-sec^(2)theta)/(cos ec^(2)theta+sec^(2)theta)=(3)/(4)
