Verifying Identities - Trig Problem

[From: ] [author: ] [Date: 12-09-11] [Hit: ]
..Solve for x-3° is just one of the solutions though!!......
Can someone please help me understand how
sin(4Θ + 2°) csc(3Θ + 5°) = 1, has an answer of 3°

Our professor really didn't go over identities in depth and I have a loose understanding of them but I really can't fathom this one.

This is not an identity. It is algebra.

Since csc = 1/sin you have and equation that says sin/sin = 1

This can only be true when the 2 sin values are the same, therefore 4theta + 2 must equal 3theta +5

Set those 2 values equal to one another in an equation and solve for theta.

4x + 2 = 3x + 5...Solve for x

3° is just one of the solutions though!!
