z= pcos(phi)
z= sqrt(x^2+y^2+z^2)cos(phi)
z^2 = (x^2 +y^2 +z^2)cos^2(pi/6)
z^2 = 3/4(x^2 +y^2 +z^2)
z^2/4 = 3/4(x^2 +y^2)
z^2 = 3(x^2 +y^2)
z = sqrt(3)sqrt(x^2 + y^2)
Find an equation in rectangular coordinates of the quadric surface consisting of the following two cones.
I havent a CLUE how to start this
please help
i was thinking of converting the cones via the normal conversion methods, but then i lost myself
ive never dealt with conical surfaces in any spaces...
