Please read each question carefully, show all work to receive the credit. a4f 1. Find yaxg and dy20xz for the function f(x,yby using. ??0x2 symbolic function command. 2. Develop the M file by parameterizing the given surface and use the parameterization to plot, 9x2 4y2-36z236, 0sts 2Tt,0 S ss 2Tt and - 5szs 5. Also label all axes and graphs should have a title that includes your name. Publish your output to HTML. 3. Develop the M file to draw the contour curve and surface together of the function /(r, y) in the square defined 5sy s5. Also label all the axes and graph should have a title that includes your name. Publish your output to HTML 4. Draw the helix given by the parametric equation x cos (2t)) sin(3 t), z- t when t varies from 0 to 47T. Also label all the axes, and graph should have a title that includes your name and use view command. Publish your output to HTML. 5. Draw the surface x2 + 25y2 + 4z2-100 0 by parameterizing it. And also on the same graph plot the normal vectors (gradient vectors). You must label all the axes and graph should have a title that includes your name. Publish your output to HTML
