Y = -3 
-3 + 3 = 0
It is impossible to divide a number by 0
        
             
        
        
        
<span>3-2(Cosx)^2 - 3Sinx = 0.
Recall (Sinx)^2 + (Cosx)^2  = 1.
Therefore  (Cosx)^2 =  1 - (Sinx)^2 
Substitute this into the question above.
</span><span>3-2(Cosx)^2 - 3Sinx = 0

1 + 2(</span><span>Sinx)^2  - 3Sinx  = 0  Rearrange
2(Sinx)^2 </span><span><span>- 3Sinx + </span>1  = 0  
Let p = Sinx
2p^2  -  3p + 1  = 0    Factorise the quadratic expression
2p^2 - p - 2p +1 = 0
p(2p -1) - 1(2p -1) = 0
(2p-1)(p -1) = 0
Therefore  2p-1=0    or  (p-1) = 0
2p=0+1    or  (p-1) = 0
2p=1       or    p = 0 +1.
p=1/2       or  p = 1            Recall p = Sinx
Therefore Sinx = 1/2 or 1.
For  0<u><</u>x<u><</u>360
Sinx =1/2,  x = Sin inverse (1/2) , x = 30,  
                                   (180-30)- 2nd Quadrant = 150 deg
Sinx = 1,  x = Sin inverse (1) , x = 90
Therefore x = 30,90 & 150 degrees.
