If tan (theta/2) = sqrt((1-e)/(1+e)) tan(phi/2),then show that cos phi=(cos theta-e)/(1-ecos theta).
The cotangent is the inverse function of the tangent, that is, when the tangent is: {eq}\tan\theta=\frac{opposite}{adjacent} {/eq} the cotangent is: {eq}\cot\theta=\frac{adjacent}{opposite} {/eq}. Both functions are related as follows: {eq}\cot\theta=\frac{1}{\tan\theta} {/...
