tangent at specific point

i plotted parametric curve r(t)=<t , t^2 , 2>, now i have to plot tangent at 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(1)
plot3(st,ct,repmat(2,1,numel(t)))
hold on

So what is dr/dt, evaluated at t = -1 ?

Answer 1

please help me.

I did. I posted a link to a tutorial explaining about the link between tangent lines and derivatives and pointed you to the way to calculate the tangent at the point.

bro i dont ask you about derivatives and tangent lines tutorial. i ask about how can i implement it into a code. stop posting tutorials of calculus to me.

Step 1: calculate the slope of the tangent line at that point.

Step 2: create a 3D plot using that slope.

Have you completed Step 1 yet? If so then what result did you get?

Are you having difficulty with the plotting stage? If so then what have you found out about how to plot 3D lines in MATLAB ?
