I'm given

cosx (tanx) = 0

and

2cos^2x + sin x = 2

The first one i did...

cosx ( sinx / cosx ) = 0

then i got rid of the cosx from sinx / cosx and got...

cos^2x ( sinx ) = 0

is that even right? D: Am I just solving for x or what? D:

for 2cos^2x + sin x = 2 ...

i moved sinx over to the 2... 2cos^2x = 2-sinx

then changed it the cos^2 to.. 2( 1-sin^2x) = 2-sinx

Am i doing these right in the first place..?
