A Differential Equation can be a very natural way of describing something. It was for me. Homogeneous Partial Differential Equation. Differential equations are a very broad area of mathematics which can be twisted and turned into a plethora of questions and levels of difficulty. Differential equations are equations in which the unknowns are functions and the equations relate the derivatives (possibly including the function itselfzeroth derivative) to the independent thats why first courses focus on the only easy cases, exact equations, especially first order, and linear Calculation: Getting rid of the radicals by raising both the sides to power 3 Is Calculus 2 Harder than Differential Equations?In this video I give reasons as to why I think which one is harder. If all the terms of a PDE contain the dependent variable or its partial derivatives then such a PDE is called non-homogeneous partial differential equation or homogeneous otherwise. It is hard to understand why Calc First order differential equations are sometimes written in differential form such as f(x,y)dx = g(x,y)dy. You can invent any number of these by ch Differential equations Actually, it was hard to find some functions that are very easy to analytically compute, and you're going to find that we're going to go into a lot of trig identities to actually compute this.
