Question

if costheta - tan²theta=1 find sec4 theta+sin²theta

Answer 1

Answer:

1 is the answer

Step-by-step explanation:

cosα-tan²α=1

so. cosα=1+tan²α

cos α=sec²α

cosα=1/cos²α

cos³α=1

taking cube root both sides

cos α=1

we get α=0 degree

so we have to find

sec^4 α+sin²α............eq 1

putting α=0 degree in eq 1

1+0=1. ( sec0=1)

( sin0=0)

so 1 is the answer
