coordenadas polares esféricas de uma olhada.....yap?

1- dada a curva descrita em pelas equacoes (x+2)^2 +(y-3)^2 =13 em cartesianas obter a equacao em coordenadas polares

2- dada a curva descrita pela equacao tg @ = 5 em cilindricas, obter a equacao em coordenadas retangulares

3 - dada a curva descrita pela equacao x^2 + y^2 + z^2 + 8x + 9y+ 10z + 40 = 0 em retangulares, obter a equacao em coordenadas esfericas e identificar o lugar geometrico
