		De verdubbelingsformule herschrijven we nu als
		\begin{align}
			\cos(2\theta) = \cos^2(\theta) - \sin^2(\theta)\\
			= 2\cos^2(\theta)-1.
		\end{align}

\begin{saveblock}{alignEN}
	\begin{highlightblock}[gobble=8,linewidth=\textwidth,
		framexleftmargin=0.25em,xleftmargin=0.25em]
		The double-angle formula can now be rewritten as
		\begin{align}
			\cos(2\theta) = \cos^2(\theta) - \sin^2(\theta)\\
			= 2\cos^2(\theta)-1.
		\end{align}
