## How do you do mixing problems?

Solving a percent mixture problem can be done using the equation Ar = Q, where A is the amount of a solution, r is the percent concentration of a substance in the solution, and Q is the quantity of the substance in the solution.

## What are differential equation models?

Differential equation models are used in many fields of applied physical science to describe the dynamic aspects of systems. The typical dynamic variable is time, and if it is the only dynamic variable, the analysis will be based on an ordinary differential equation (ODE) model.

**Is differential equations the hardest math class?**

I would say they’re roughly equal in difficulty. Differential equations will require more memorization of techniques, but you might find them very intuitive. There will be very few proofs. This is probably because they’re too advanced for a first course.

**How to solve differential equations?**

– Compare the terms in f ( x) {\\displaystyle f (x)} with the terms in y c, {\\displaystyle y_ {c},} disregarding multiplicative constants. There are three cases. – Write out y p {\\displaystyle y_ {p}} as a linear combination of the aforementioned terms. – Solve for the coefficients. – Example 2.3.

**What is a particular solution differential equation?**

The particular solution of a differential equation is a solution which we get from the general solution by giving particular values to an arbitrary solution. The conditions for computing the values of arbitrary constants can be given to us in the form of an initial-value problem or Boundary Conditions depending on the questions.
