Need help with a problem

[Guest]

Hello, we got assigned a trigonometry homework which may be graded, but the problem is we haven't already done that, so I don't know how to solve it. It's only one equation:

sin^2(x+1) = 3sin(cosx-sinx)+3

I'd be grateful if you could guide me through the solving process. English is not my native language, so sorry for any mistakes. Thanks in advance.

I would like to suggest you to check out some examples to understand the proper process of solving such kind of problems. If you will find the answer here you will never try to understand it by yourself. Your teacher has given the homework so that you can try to solve it by yourself. Try it first by yourself and if you face some problem then you should ask your teacher to explain it.

Is this not a help forum??

It seems that there is something wrong with the problem.

There may be a problem with the problem.?

sin^2(x+1) = 3sin(cosx-sinx)+3

What's the problem with the problem.?
It reads sin squared (x+1) = [3 times [sin of (cosx - sinx)]] + 3

it is cyclic so various values for x satisfy.

x = 2.334 and x = 3.331 radians satisfy the equation.
