Can you answer this?: tan(x + 45) - tanx = 4

Giving the values of x in the ineterval -180<x<180

Giving the values of x in the ineterval -180<x<180

Expand tanx using

tan(A+B) = \frac{tanA + tanB}{1-tanAtanB}

Expand tanx using

tan(A+B) = \frac{tanA + tanB}{1-tanAtanB}

straight forward from there..

I think that's right. Thought I'd do it, was bored.
