Passi tas-Soluzzjonijiet

Ikkalkula 1 bil-power ta' 4 u tikseb 1.

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

Kwalunkwe ħaġa diviża b'wieħed tagħti riżultat tagħha stess.

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

Ikkalkula 2 bil-power ta' 4 u tikseb 16.

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

Ikkalkula 3 bil-power ta' 4 u tikseb 81.

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

Iffattura 'l barra \frac{1}{1296}.

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

Evalwa
