## anonymous one year ago Trig/Pre Cal/identities Where do I start with this? Do not give answer. Just need to know where to start? I am not sure. $$\frac{cos x}{1-sin x}=\frac{1+sin x}{cos x}$$ Thank you

I would multiply the left side by $\frac{ 1 + \sin x }{ 1 + \sin x}$ because $\cos^2 x = 1 - \sin^2 x$

$$1- \cot x=\frac{1+\sin x}{\cos x}$$ ?

Ok, let me work it from there
