(a) what is the period of the forced oscillation? what is the numerical value (modulo 2π) of the angle α defined by (l6.4)? (b) in this question you are asked to modify the file lab06ex1.m in order to plot the complementary solution of (l6.1), that is, the first term in (l6.2). first define in the file the angle α (alpha) using (l6.4), then evaluate the complementary solution yc by subtracting the quantity c cos(ωt − α) from the numerical solution y. plot the resulting quantity. does it look like an exponentially decreas

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

the anwser is d) 75°
