Explain why you cannot square each side of the equation when verifying a trigonometric identity.
Sergeu [11.5K]
This is because when we do verification of an identity, we must work separately on both sides, and to see in the end if we can get an equality. Because if we square both sides, that already means that we assume that the equality exist in the beginning, so no need to verify the identity.
