Sin3A-SIN2A equal to zero then what is the value of A
----------
Is it sin^3(A) - sin^2(A) ?
or sin(2A) - sin(3A) ?

.
If your equation is sin(3A) = sin(2A) then
3A + 2A = ,
5A = ,
A = , or
A = = 36°.
--------------------------------------------------
O! There is one more solution: A = 0, but it is not so interesting.
A = 180° is the solution also, by the way.
