Homework Statement:

If tanx = 4/3 and π < x < 3π/2 , evaluate the following
(Sinx2cosx) / (cotxsinx)
Relevant Equations:

Tan x=sinx/cosx
Cotx=1/tan
(Sinx2cosx)/ (cotx  sinx)
Substitute tan instead of cot
(Tanx(sinx2cosx)/(1sinx)
What do I do from here
I don't think what I did there is correct
That's why I didn't expand the tan to sin/cos
