Whakaoti i te 2tan2(1+operatorname{ctan}2)^2

$$2 \tan 2 ( 1 + \operatorname { ctan } 2 ) ^ { 2 }$$

Aromātai

$$\frac{2\tan(2)\left(\sin(2)c+\cos(2)\right)^{2}}{\left(\cos(2)\right)^{2}}$$

Ngā Upane Otinga

Whakamahia te ture huarua \left(a+b\right)^{2}=a^{2}+2ab+b^{2} hei whakaroha \left(1+c\tan(2)\right)^{2}.

$$2\tan(2)\left(1+2c\tan(2)+c^{2}\left(\tan(2)\right)^{2}\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 2\tan(2) ki te 1+2c\tan(2)+c^{2}\left(\tan(2)\right)^{2}.

$$2\tan(2)+4\left(\tan(2)\right)^{2}c+2c^{2}\left(\tan(2)\right)^{3}$$
