$f(\theta )=\sin(\theta )$

$f(2\theta )$

$f(2(60^{\circ })=120^{\circ }$ Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://en.wikipedia.org/api/rest_v1/":): {\displaystyle f(2\theta)= f(2\cdot\60) }

sin(120^\circ)= \frac{\sqrt{3}}{2}
