Question 236334: use the fundamental identities to simplfy csc^2(beta)((1-cos^2(beta))

Recall that +\cos^2(x)=1)
. So =1-\cos^2(x))
. Also, remember that =\frac{1}{\sin(x)})
So in this case, )
becomes )
and )
turns into })
So \left(1-\cos^2(\beta)\right))
simplifies to }\sin^2(\beta))
which then becomes }{\sin(\beta)})
and finally simplifies to )
In the end, \left(1-\cos^2(\beta)\right)=\sin(\beta))
