Question

(sin^2(theta)+cos^2(theta) )/cos^2(theta)=sec^2(theta)

Answer 1

sin^2(theta)+cos^2(theta)=1
1/cos^2(theta)=sec^2(theta)
Does that help? @messinalexy

Answer 2

not really. but i dont really understand math at all so its not your fault

Answer 3

I guess u need to prove that identity.
let us take the expression on the left side of the equation.
(sin^2(theta)+cos^2(theta) )/cos^2(theta) and show that it is equal to sec^2(theta).
sin^2(theta)+cos^2(theta)=1
1/cos^2(theta)=sec^2(theta)

Answer 4

okay
