General Solutions

I know this isn't about surface area of a cone lol, i found the answer to that but hear me out..

Is the general solution for sinx:
n.pi + (-1)^n.alpha OR
n.pi.(-1)^n +alpha?

Could someone please help me?

The first one is correct, npi + (-1)^n.@

general solution of sinx=@ is
x=(-1)^m sin^-1 @+mpi integer m

x=(-1)^m sin^-1 @+mpi integer m

What on earth is that lol, some 4 unit stuff?
EDIT: silly me, lol its just the way to find @
