To determine The solutions to the differential equations d q − 4 q d u = 2 d u at q = 2 when u = 0 . Explanation Procedure used: The solution of a differential equation of the form d y + P y d x = Q d x is y e ∫ P d x = ∫ Q e ∫ P d x d x + c . Where e ∫ P d x is called integration factor, P and Q are functions of x only. Calculation: To solve as a first order equation is d q − 4 q d u = 2 d u . Now compare the obtain differential equation to d y + P y d x = Q d x . The value of P is − 4 , Q is 2 , y is q and x is equal to u . So, the value of Integrating factor is calculated as: I .F . = e ∫ P d u = e ∫ − 4 d u = e − 4 u Then the solution of differential equation is calculated as: y e ∫ P d x = ∫ Q e ∫ P d x d x + c q e − 4 u = ∫ 2 e − 4 u d u + c q e − 4 x = 2 ∫ e − 4 u d u + c Suppose that − 4 u = t and further simplification of above obtain differential equation. − 4 u = t − 4 d u = d t d u = − d t 4 Evaluate the proper change in differential equation
