W\times 2=\frac{1}{2}\sin(0,8\pi )

Margfaldaðu 0,4 og 2 til að fá út 0,8.

2W=\frac{\sin(\frac{4\pi }{5})}{2}

Jafnan er í staðalformi.

\frac{2W}{2}=\frac{\sqrt[4]{5}\sqrt{2\sqrt{5}-2}}{2\times 8}

Deildu báðum hliðum með 2.

W=\frac{\sqrt[4]{5}\sqrt{2\sqrt{5}-2}}{2\times 8}

Að deila með 2 afturkallar margföldun með 2.

W=\frac{\sqrt[4]{5}\sqrt{2\sqrt{5}-2}}{16}

Deildu \frac{\sqrt[4]{5}\sqrt{2\sqrt{5}-2}}{8} með 2.
