    csc = 1/sin, replace it, first, then I guide you more

    csc(x)*sin(x)=(1/sin(x))sin(x) = 1 cos^2(x)/sin^2(x) = cot^2(x) so cot^2(x) + 1 now how can we get that out of cos^2(x)+sin^2(x)=1 divide everything by sin^2(x) cot^2(x)+1 = (1/sin^2(x)) = csc^2(x)

    skipping the fraction for a second \[\frac{ 1 }{ \sin(\theta) }*\sin(\theta)=1\]

    and now \[\frac{ \sin^2(\theta) }{ \cos^2(\theta) }=\tan^2(\theta)\]
