Kua tāruatia ki te papatopenga
xf=\cot(x)-\sqrt{x}
He hanga arowhānui tō te whārite.
\frac{xf}{x}=\frac{\cot(x)-\sqrt{x}}{x}
Whakawehea ngā taha e rua ki te x.
f=\frac{\cot(x)-\sqrt{x}}{x}
Mā te whakawehe ki te x ka wetekia te whakareanga ki te x.
f=\frac{\frac{\cot(x)}{\sqrt{x}}-1}{\sqrt{x}}
Whakawehe \cot(x)-\sqrt{x} ki te x.
