Cyfrifo 1 i bŵer 4 a chael 1.

$$factor(\frac{\sin(x)}{1}-\frac{\sin(2x)}{2^{4}}+\frac{\sin(3x)}{3^{4}})$$

Mae rhannu unrhyw beth ag un yn rhoi'r rhif hwnnw.

$$factor(\sin(x)-\frac{\sin(2x)}{2^{4}}+\frac{\sin(3x)}{3^{4}})$$

Cyfrifo 2 i bŵer 4 a chael 16.

$$factor(\sin(x)-\frac{\sin(2x)}{16}+\frac{\sin(3x)}{3^{4}})$$

Cyfrifo 3 i bŵer 4 a chael 81.

$$factor(\sin(x)-\frac{\sin(2x)}{16}+\frac{\sin(3x)}{81})$$

Ffactora allan \frac{1}{1296}.

$$\frac{1296\sin(x)-81\sin(2x)+16\sin(3x)}{1296}$$
