Algebraic solution of an equation, comparing a coefficients method

Vote count: 0

I have really big problem solving equations like this one (simplified one):

acos(x) + bsin(x) = cos(x) + sin(x), with respect to a,b.

In the equation can stand expressions of: sin(x), cos(x), exp(C*x) and polynomials.

I need to get solution in this form: [a b] = [1 1].

Only solution I can reach now is: b = 0, a = (cos(x) + sin(x))/cos(x).

I was trying hard to find something, but I did not find anything. I really appreciate any help! Thank you!
