In the example of using mesh command to plot z re, where 0 s e s 360 and 0 S r s 2, we have the following code [th, r].meshgrid ( (0: 5: 360) *p? / 180, 0: . 1:2) ; (X, Y] po12cart (th, r) ; mesh (X, Y, Z) Which of the following statements can replace [x, Y] po12cart (th, r)2 a. X-T. cos(th); y-r."sin(th) b. x-r cos(th); y-r sin(th): X=r*cos(th); Y-rsin(th) X-r*cos(th); Y-r. 'sin(th); c, d. 10. Which one of the methods will be appropriate for the interpl command in the following code? y [1.0 -0.6242 -1.4707 3.2406 -0.7366-6.3717]: xi-6:0.1:8 yl-interp1 (x,y,xi, 'methodName) a. nearest b. linear c. spline d. None of the above

Explanation / Answer

8. [k1,k2] = polyder(p1,p2) gives the derivative of the quotients of the polynomail with coefficients p1 and p2.

9.(d)

We need array multiplication. So the dot operator is used. Kindly notice that in first two options the variables are in lower case.
