At what points does the helix r(t)=<\sin t, \cos t, t> intersect the …
WEBOct 30, 2021 · We have to find points where helix r (x) = sin t, cos t intersects the sphere x 2 + y 2 + z 2 = 5. Take each vector component from the given vector and plug it into the sphere's equation (x = vector's x − component, y = vector's , y − component, z = vector's , z − component) In this way, we get,
