Homework Statement
r(t) = sin t (i) + cos t (j) + t (k)
(a) Graph the vector function
i = x
j = y
k = z
Is this correct.
Since t is in the Z direction. I'm going to assume that this graph is parallel to the XY plane.
Now I'll take
x = sin t
y = cost t
Then if you square both of these functions.
so then we get x^2 + y^2 = (sin t) ^ 2 + (cos t) ^ 2
Then this becomes x^2 + y ^2 = 1
So it's a circle. Right. Is it going to be a spring or coil on the z - axis.
