I don´t know how to explane it. When i put in Mathematica a and b 45deg (a=b=45deg)
I'm very interested in knowing what c stands for?
At first i woul like to thank you for your help.
If you want c to be a maximum, and c is in the function, then we are missing something ... perhaps this function is equal to a constant?
1/4(2+Cos[2(a-b)]+Cos[2(a+b)]-2Cos[c]Sin[a]Sin) <- something seems wrong here
The cosine and sine functions are periodic, so they have infinitely many maximums. The period of both is pi radians (180 degrees), though cos begins pi/2 radians to the left of sin. So, at every increment of pi/2, either sin or cos has a maximum.
