WebbHint: cos(2x) = cos(x+x) = cosxcosx −sinxsinx = cos2x −sin2x = cos2x −(1−cos2x) = 2cos2 x−1 So, cos2x = 21+cos(2x) which can be substituted. For which a ∈ R are … WebbSimplify (sin(x)+cos(x))^2.

WebbNotice that \cos^{2}(x):=(\cos(x))^{2} is not the same thing as \cos(2x). It is indeed true that \sin^{2}(x)=1-\cos^{2}(x) and that \sin^{2}(x)=\frac{1-\cos(2x)}{2}. Webb$\begingroup$ Seems like you simplified $\sin^4 x - \cos^4 x$, not $\sin^4 x + \cos^4 x$. $\endgroup$ – lisyarus.
