Trig

The next two steps in solving this trig identity question are ???
1/csctheta x costheta x sintheta x sectheta = sinsqtheta
arghhh need help please

first : 1/csc t = 1/(1/sin t) = sin t
sin t * cos t * sin t * 1/cos t
is
sin^2 t

It would help if you learn conventional notation
x^2 is x squared
x^3 is x cubed
sqrt x or x^.5 is square root x
* is times
Use parentheses especially for multi term denominators and numerators
No need to type theta out, use t or z or p or something. It does not matter as long as you do not have the same letter for something else.
