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 = pi,

5A = pi,

A = pi%2F5,       or

A = 180%5Eo%2F5 = 36°.

--------------------------------------------------

O!  There is one more solution:  A = 0,  but it is not so interesting.

A = 180° is the solution also, by the way.
