Matlab projects

Hi there! I make math videos on YouTube. I’m hoping to find someone who is great at math, and also great at Matlab! I will want someone that I work well with, since I hope to make many videos. Here is the first task. I need to graph a surface. Let’s say z=f(x,y)=x^2-y^2. Then, I need to see the image of (g(t),h(t)) on that surface, where g(t)=e^t and h(t)=sin(t). LEt’s only concern ourselves with t values from 0 to 2pi. Finally, I would like to help students visualize how the derivative is defined for points along this surface (but restricted to the image of the aforementioned parametric condition). To do this, I’d like to graph the line between (g(t),h(t)) and (g(t+a),h(t+a)) and have a slider so I can show them what happens to this line, in 3D, as a -> 0. Please include your quote, and any screenshots of your finished work! Happy to answer any questions. Cheers, Sheldon
