Question

Tan theta = 1/√5 , find the value of (cosec^2 theta - sec^2 theta) / (cosec^2 theta + sec^2 theta)

Answer 1

Step-by-step explanation:

multiplying the numerator and denominator with sin^2 theta you get everything in terms of tan theta which on solving gives2/3

Answer 2

Answer:

25/6

• Since tan theta is 1/root5

So we can find the values of Cosec and sec theta

Cosec theta=root6, cosec sq theta=6

Sec theta=root6/root5, sec sq theta=6/5

solution:

cosec2theta -sec2 theta/1 Since(cosec2 theta+sec2 theta=1)

After putting values of cosec theta and sec theta:

=》 6-6/5

=》25/6
