In this paper we introduce and study exact fractional differential equations, where we use the conformable fractional derivative. This forces us to introduce the fractional differential of functions.
Using the differential geometry of vector fields and forms we reinterpret and extend the traditional idea of an integrating factor for a first order differential equation with symmetry. In

We will derive the solutions for homogeneous differential equations and we will use the methods of undetermined coefficients and variation of parameters to solve non homogeneous differential equations. In addition, we will discuss reduction of order, fundamentals of sets of solutions, Wronskian and mechanical vibrations.
Chapter 1 First–Order Differential Equations A differential equation is an equation that contains one or more derivatives. For example, y′′(x)+x3y′(x)+y5(x)=10cos(4x)
Some second‐order equations can be reduced to first‐order equations, rendering them susceptible to the simple methods of solving equations of the first order. The following are three particular types of such second-order equations: Type 1: Second‐order equations with the dependent variable

linear, second order ordinary diﬀerential equations, emphasizing the methods of reduction of order and variation of parameters, and series solution by the method of Frobenius.
The classical reduction of order for scalar ordinary differential equations (ODEs) fails for a system of ODEs. We prove a constructive result for the reduction of order for a system of ODEs that admits a solvable Lie algebra of point symmetries.
So, for ‘sufﬁciently simple’ differential equations, you may still prefer using the guess method instead of what we’ll develop here. We will ﬁrst develop the variation of parameters method for second-order equations.
