(1 point) match the following guess solutions yp for the method of undetermined coefficients with the second-order nonhomogeneous linear equations below. a. yp(x)=ax2+bx+c, b. yp(x)=ae2x, c. yp(x)=acos2x+bsin2x, d. yp(x)=(ax+b)cos2x+(cx+d)sin2x e. yp(x)=axe2x, and f. yp(x)=e3x(acos2x+bsin2x) 1. f d2ydx2+4y=x−x220 2. b d2ydx2+6dydx+8y=e2x 3. c y′′+4y′+13y=3cos2x 4. d y′′−2y′−15y=3xcos2x

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

hope it

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

a
