For all of the graphs below use a vector x ranging from 0 to 10 in steps of 0.1.

For all of the graphs below use a vector x ranging from 0 to 10 in steps of 0.1. Create two additional vectors using the following formulas: yp=x.^2.5 and ym=x.^(-2.5);

[1;2] Create the formula for the derivative of yp (apply the rules of calculus to the formula for yp). Plot yp versus x. Add a straight line at 3 points (at x = 3, 5, 8) with the slope of the line (determined from the derivative) showing that the derivative is the slope of a tangent line at the indicated points.

Below is a proof of Theorem 4.1.1 (b): For the zero vector ⃗0 in any vector space V and k ∈ R, k⃗0 = ⃗0. Justify for each of the eight steps why it is true. k⃗0+k⃗0=k(⃗0+⃗0) = k ⃗0 k⃗0 is in V and therefore −(k⃗0) is in V . It follows that (k⃗0 + k⃗0) + (−k⃗0) = (k⃗0) + (−k⃗0) and thus k⃗0 + (k⃗0 + (−k⃗0)) = (k⃗0) + (−k⃗0). We conclude that k⃗0 + ⃗0...
