Determine whether each first-order differential equation is separable, linear, both, or neither. 1. ????y????x+????xy=x2y2 2. y+
Mkey [24]

Answer:

a) Linear

b) Linear

c) Linear

d) Neither

See explanation below.

Step-by-step explanation:

a) \frac{dy}{dx} +e^x y = x^2 y^2

For this case the differential equation have the following general form:

y' +p(x) y = q(x) y^n

Where p(x) =e^x and q(x) = x^2 and since n>1 we can see that is a linear differential equation.

b) y + sin x = x^3 y'

We can rewrite the following equation on this way:

y' -\frac{1}{x^3} y= \frac{sin (x)}{x^3}

For this case the differential equation have the following general form:

y' +p(x) y = q(x) y^n

Where p(x) =-\frac{1}{x^3} and q(x) = \frac{sin(x)}{x^3} and since n=0 we can see that is a linear differential equation.

c) ln x -x^2 y =xy'

For this case we can write the differential equation on this way:

y' +xy = \frac{ln(x)}{x}

For this case the differential equation have the following general form:

y' +p(x) y = q(x) y^n

Where p(x) =x and q(x) = \frac{ln(x)}{x} and since n=0 we can see that is a linear differential equation.

d) \frac{dy}{dx} + cos y = tan x

For this case we can't express the differential equation in terms:

y' +p(x) y = q(x) y^n

So the is not linear, and since we can separate the variables in order to integrate is not separable. So then the answer for this one is neither.
