Camau Ateb

Cael gwerth \sin(45) o’r tabl gwerthoedd trigonometrig.

$$\frac{\left(\frac{\sqrt{2}}{2}\right)^{2}}{m}$$

I godi \frac{\sqrt{2}}{2} i bŵer, codwch y rhifiadur a'r enwadur i bŵer ac yna rhannwch nhw.

$$\frac{\frac{\left(\sqrt{2}\right)^{2}}{2^{2}}}{m}$$

Mynegwch \frac{\frac{\left(\sqrt{2}\right)^{2}}{2^{2}}}{m} fel ffracsiwn unigol.

$$\frac{\left(\sqrt{2}\right)^{2}}{2^{2}m}$$

Sgwâr \sqrt{2} yw 2.

$$\frac{2}{2^{2}m}$$

Cyfrifo 2 i bŵer 2 a chael 4.

$$\frac{2}{4m}$$
