I have position vector
r(t)=<t , t^2 , 2>,
I have to plot it using plot3 function and also plot tangent at the point P(-1 , 1, 2) but I cant figure it out. Can you help me please?
t = 0:pi/50:10*pi;
st = t;
ct = t.^2;
figure
plot3(st,ct,2)

We're getting there, but not quite. So are you saying that
- i, which is x, goes from some unspecified negative number up to 0
- j, which is y, goes from some negative, unspecified t to some positive, unspecified t
- k, which is z, goes from 2 up to some unspecified max z value.
Can you specify the unspecified range limits?

Make the vectors the same length then exactly as the error message tells you! 2 is a scalar, each component of your vector represents x, y & z.
plot3(st,ct,repmat(2,1,numel(t)))
