Question

Is csc squaredx + cot squaredx=1 a identity?

Answer 1

No,
\[ \csc^2(x) + \cot^2(x) = \frac{1+\cos^2(x)}{\sin^2(x)}\]

Answer 2

so is (cscx+cotx) squared=1 an identity? i dont understand how to solve them

Answer 3

no, but 1 + cot^2 = csc^2 is an identity

Answer 4

What do you mean, how to solve them?

Answer 5

ii dont understand how to see if their identities or not. I have asked my teacher but he doesnt explain anything to me.

Answer 6

The fundamental identity is
\[ \sin^2(x) + \cos^2(x) = 1\]
All of the other identities follow from that. Write things in terms of sin and cos and see what happens.
