# Curly waves

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

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