I am trying to figure out how I can solve for the following in Mathematica:
cos[x+4]=sin[3x+2] where the angle is acute (90>x>0)
I tried to use Solve, but how do I restrict solve to only angles less than 90 degress but greater than 0? The solution is 21 degrees, but I am having a hard time in figuring how to get Mathematica to do this, i thought maybe I could do something like:
Solve[cos[x+4]=sin[3x+2] , x /; 90>x>0]
but that doesn't seem to work. Any ideas?
