The polar equation r 4 csc theta has the rectangular form

____ The polar equation r = 4 csc theta has the rectangular form ____ The polar equation r = 30 + 25 cos theta has symmetry about ____ vector PQ has initial point (3, 1, 4) and terminal point (5, -1, 3) then ||PQ|| = ___ If cos theta = 3/4 and theta is the angle between vectors u and v and the magnitude of vector u is 12 and the magnitude of vector v is 10 then u v = ____ If u = -3i + 2j and v = 7i - j then 2u - 3v =

Solution

6. r=4csc theta

r=4/sin theta

rsin theta=4

y=4

The rectangular equation is y=4
