Determine as coordenadas cartesianas do ponto \( P \), cujas coordenadas polares são \( \left(2, \frac{\pi}{6}\right) \). Expresse em coordenadas cilíndricas o ponto \( (2,2,4) \). Expresse em coordenadas cilíndricas a equação \[ x+y+z=1 . \] Expresse em coordenadas esféricas a esfera \( S: x^{2}+y^{2}+z^{2}=a^{2} \), de centro na origem e raio \( a \). Os seguintes pontos são dados em coordenadas cartesianas, encontre suas representações - \( (1,1,1) \) - \( (1,-1,1) \) - \( (-1,1,1) \) - \( (-1,-1,1) \) Se um ponto \( P \) tem coordenadas esféricas: de \( P \).

Quick Answer

1. Coordenadas cartesianas do ponto \( P \): \( \left(\sqrt{3}, 1\right) \). 2. Coordenadas cilíndricas do ponto \( (2, 2, 4) \): \( \left(2\sqrt{2}, \frac{\pi}{4}, 4\right) \). 3. Equação \( x+y+z=1 \) em coordenadas cilíndricas: \( r(\cos(\theta) + \sin(\theta)) + z = 1 \). 4. Equação da esfera \( S: x^{2}+y^{2}+z^{2}=a^{2} \) em coordenadas esféricas: \( \rho = a \). 5. Representações dos pontos em coordenadas esféricas: - \( (1, 1, 1) \): \( \left(\sqrt{3}, \frac{\pi}{4}, \frac{\pi}{3}\right) \). - \( (1, -1, 1) \): \( \left(\sqrt{3}, -\frac{\pi}{4}, \frac{\pi}{3}\right) \). - \( (-1, 1, 1) \): \( \left(\sqrt{3}, \frac{3\pi}{4}, \frac{\pi}{3}\right) \). - \( (-1, -1, 1) \): \( \left(\sqrt{3}, \frac{7\pi}{4}, \frac{\pi}{3}\right) \).
