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..?
