Question

sec ^4 theta -sec^2 theta +tan^2 theta​

Answer 1

Step-by-step explanation:

Sec⁴ theta - Sec² theta + tan² theta

Sec² theta (Sec² theta - 1) + tan² theta

Sec² theta (1 + tan²theta - 1) + tan²theta

Sec²theta * tan²theta + tan² theta

tan²theta(Sec²theta + 1)

tan²theta ( 2 + tan² theta)

2tan² theta + tan⁴ theta
