Can someone help me to solve this equation
They ask Show that the equation 2tan^2xcosx=3 can be written in the form 2cos^2x+3cos-2=0
I got it right so far to make everything cos but not without the ^2
here is what i did:
2tan^2xcosx =3
---------------------------------------------------------------------------------
2sin^2x
---------- cosx = 3
2cos^2x
---------------------------------------------------------------------------------
2-2cos^2x
------------
2cos^2
