Question

prove that sec²(90°-theta)+tan²90°-theta)=cosec²theta+cot²theta

Answer 1

Answer:

its true

Step-by-step explanation:

Answer 2

Step-by-step explanation:

sec(90-theta)=cosec theta

tan (90-theta)=cot theta

so... by using the identities.

putting the values of these. and, then

we get

cosec²theta+cot²theta
