A linear first order ordinary differential equation is that of the following form, where we consider that y = y(x), and y and its derivative are both of the first degree. \\frac{\\mathrm{d}y}{\\mathrm{d}x} + P(x)y = Q(x) To solve this

For this DE, we introduce the integrating factor. Linear Differential Equation A differential equation is linear, if 1. dependent variable and its derivatives are of degree one, 2. coefficients of a term does not depend upon dependent variable. Example: 36 4 3 3 y dx dy dx yd is non - linear because in 2nd term is not of degree one. .0932 2 y dx dy dx ydExample: is linear.

The equation is in the standard form for a first‐order linear equation, with P = t – t −1 and Q = t 2. Since . the integrating factor is. Multiplying both sides of the differential equation by this integrating factor transforms it into . As usual, the left‐hand side automatically collapses, and an integration yields the general solution:

Find the integrating factor . 3. Some simple control systems (which includes the control of temperature, level and speed) can be modelled as a first-order linear differential equation: (3.5)τdY dt + Y = kX where X and Y are the input and output, respectively, τ denotes the system time constant and k is the system gain.
