Question

d/dx(px+q)=? Pls urgently solve this​

Answer 1

d/dx(px+q) = p

hope it helped you

Answer 2

Ans- A differential equation of the from dy/dx + Py = Q

where, P and Q are constants or functions of x only, is known as a first order linear differential equation.

Example:

Another form of first order linear differential equation can be dx/dy+ Px =Q

where, P and Q are constants or functions of y only, is known as a first order linear differential equation

Steps involved to solve first order linear differential equation:

(i) Write the given differential equation in the form dy/dx + Py = Q , where P, Q are constants or functions of x only.

(ii) Find the Integrating Factor (I.F)

(iii) Write the solution of the given differential equation as

y (IF) =∫Q + IF. dx + C

Problem: Solve equation: dy/dx + y/x = x2

Solution. The given differential equation is in the form of dy/dx + Py = Q

(Here P=1/x and Q=x2)

This is the required general solution of the given differential equation.
