Forma polare di $$$15625 + \frac{719413999 i}{1000000000}$$$
Il tuo input
Trova la forma polare di $$$15625 + \frac{719413999 i}{1000000000}$$$.
Soluzione
La forma standard del numero complesso è $$$15625 + \frac{719413999 i}{1000000000}$$$.
Per un numero complesso $$$a + b i$$$, la forma polare è data da $$$r \left(\cos{\left(\theta \right)} + i \sin{\left(\theta \right)}\right)$$$, dove $$$r = \sqrt{a^{2} + b^{2}}$$$ e $$$\theta = \operatorname{atan}{\left(\frac{b}{a} \right)}$$$.
Abbiamo che $$$a = 15625$$$ e $$$b = \frac{719413999}{1000000000}$$$.
Quindi, $$$r = \sqrt{15625^{2} + \left(\frac{719413999}{1000000000}\right)^{2}} = \frac{\sqrt{244140625517556501957172001}}{1000000000}.$$$
Inoltre, $$$\theta = \operatorname{atan}{\left(\frac{\frac{719413999}{1000000000}}{15625} \right)} = \operatorname{atan}{\left(\frac{719413999}{15625000000000} \right)}.$$$
Pertanto, $$$15625 + \frac{719413999 i}{1000000000} = \frac{\sqrt{244140625517556501957172001}}{1000000000} \left(\cos{\left(\operatorname{atan}{\left(\frac{719413999}{15625000000000} \right)} \right)} + i \sin{\left(\operatorname{atan}{\left(\frac{719413999}{15625000000000} \right)} \right)}\right).$$$
Risposta
$$$15625 + \frac{719413999 i}{1000000000} = \frac{\sqrt{244140625517556501957172001}}{1000000000} \left(\cos{\left(\operatorname{atan}{\left(\frac{719413999}{15625000000000} \right)} \right)} + i \sin{\left(\operatorname{atan}{\left(\frac{719413999}{15625000000000} \right)} \right)}\right) = \frac{\sqrt{244140625517556501957172001}}{1000000000} \left(\cos{\left(\left(\frac{180 \operatorname{atan}{\left(\frac{719413999}{15625000000000} \right)}}{\pi}\right)^{\circ} \right)} + i \sin{\left(\left(\frac{180 \operatorname{atan}{\left(\frac{719413999}{15625000000000} \right)}}{\pi}\right)^{\circ} \right)}\right)$$$A
