so cos 2x = 0. so 2x = pi/2 or 3pi/2 . 2x = 2npi + pi/2 and 2npi + 3pi/2. x = npi + pi/4 and npi + 3pi/4 ,,,,, where n is integer.

Ja, det är två helt olika saker. 2cosx skulle jag hellre skriva som 2*cos (x), alltså Dubbelt så mycket som cosinus för x. cos2x skulle jag hellre skriva som cos (2x), alltså Cosinus för dubbla vinkeln. Om x är pi/6 radianer (samma som 30 grader) 2*cos (pi/3) = 2 * sqrt (3)/2 = sqrt (3) cos (2*pi/6) = cos (pi/3) = 1/2.

It is indeed true that \sin^{2}(x)=1-\cos^{2}(x) and that \sin^{2}(x)=\frac{1-\cos(2x)}{2}. Notice that cos 2 ( x ) : = ( cos ( x ) ) 2 is not the same thing as cos ( 2 x ) .
