Solve equation sin(x + 15 ) = 3cos(x - 15) for 0 - 360 degrees.
I started with
sinx cos15 + cosx sin15 = 3( cosx cos15 + sinx sin15)
i don't know where to go now
thanks

Put all the terms with on one side and all the terms with on the other. Then factor out and from their respective sides, so you get something like:
Now assuming and , divide everything by , and you'll need to remember a very well known trig identity here to complete the final step.
