Answer 1

Respuesta:

Explicación paso a paso:

P = $\sqrt{2}$ Cos 45° . Csc² 45°

sabemos que

$Cos 45 =\frac{\sqrt{2} }{2} \\\\Csc45=\sqrt{2}$

$P = \sqrt{2}Cos45 . Csc^{2}45\\\\P= \sqrt{2}.\frac{\sqrt{2} }{2}. (\sqrt{2})^{2} \\\\P= \frac{2}{2}.2\\\\P = 2$

E = $\sqrt{2}$ Sen² 45°

sabemos que

$Sen 45 =\frac{\sqrt{2} }{2}$

$E=\sqrt{2}Sen^{2}45\\\\E = \sqrt{2}(\frac{\sqrt{2} }{2})^{2}\\\\E= \sqrt{2}(\frac{2}{4})\\\\E = \frac{\sqrt{2} }{2}$
