Find the general solution of the given differential equation. x dy dx − y = x2 sin(x) give the largest interval over which the general solution is defined. (think about the implications of any singular points. enter your answer using interval notation.

The general solution of a differential equation is to write y as a function of x.

Given

Divide through by x

Let P be function of x. Such that:

So, we have:

Calculate the integrating factor I(x).

So, we have:

Substitute

Rewrite as:

Integrate

So, we have:

Introduce .

So, we have:

Multiply both sides by dx

Integrate with respect to x

Multiply through by x

So, the general solution is: , and the interval is

Divide both sides by . In doing so, we force any possible solutions to exist on either or (the "positive" interval in such a situation is usually taken over the "negative" one) because cannot be 0 in order for us to do this.

Condense the left side as the derivative of a product, then integrate both sides and solve for :

step-by-step explanation: 4 cause 2+2=4

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
