1. The problem statement, all variables and given/known data Given the eqn x=2, y=sin(t), z=cos(t), draw this function in 3-space. 2. Relevant equations ABOVE^ 3. The attempt at a solution I did this: x^2+y^2+z^2=2^2+(sin(t))^2+(cos(t))^2=5 Therefore we get x^2+y^2+z^2=5 Which is the eqn of a sphere with radius root5. My friend said it's supposed to be a circle but I can't see how? Which one of us is right if either.
