Curly waves

Equation of two waves are
y=Asin(wtkx)y = A \sin(wt - kx)
y=Asin(wtkx+90)y=A \sin(wt - kx + 90) 90 denotes 90 degrees,
A is amplitude,w is angular frequency, kk is wave number;

Now the equation of the resulting wave can be represented as
y=Aa2sin(wtkx+b)y = A\sqrt [ 2 ]{ a } \sin(wt - kx + b) where aa is an integer, and bb is in degrees
Find (b2)/(a5)(b*2)/(a*5).
