Question

did anyone know how to do this one?

thanks in advance ​

Answer 1

Answer:

1

Step-by-step explanation:

sin^2 theta / sin^2 theta + cos^2 theta / sin^2 theta = 1 / sin^2 theta

sin^2 theta will cancel out each other

1 + cot^2 theta = cosec^2 theta

1 = cosec^2 theta - cot^2 theta = 1

[cosec^2 theta - cot^2 theta = 1 always]

sorry but I think it's wrong
