Show that y = x is a solution of x^2y ′′ − x(2 + x cot x)y′ + Use the method of variation of parameters to find the general solution of the nonhomogeneous equation x^2y ′′ − x(2 + x cot x)y′ + (2 + x cot x)y = x^3 sin x.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

answer: i don't understand it

step-by-step explanation: sorry

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

it would not be increasing by nothing that i can see probably by 25 percent that is all i can sat\y for now if i have any thing else to say i will edit this.

step-by-step explanation:
