Undetermined Coefficients: Part 4

We’ve posted a new lesson in the
Differential Equations Vol 2 Area:

Section 15 – Non-Homogeneous ODEs – Method of Undetermined
Coefficients: Part 3

We’ve posted two new lessons in the Differential Equations, Vol 2 Area!

Section 13 – Non-Homogeneous ODEs – Method of Undetermined
Coefficients – Part 1

Section 14 – Non-Homogeneous ODEs – Method of Undetermined
Coefficients – Part 2

In this section, we conclude the example problems that involve complex
roots of linear homogeneous ODEs.

Differential Equations, Volume 2
Section 12 – Linear Homogeneous ODEs with Constant Coefficients:
Complex Root Solutions – Part 3

In this section, we continue to work problems in finding the solution of
homogeneous linear ODEs with constant coefficients and complex roots.
The resulting solutions will have sines and cosines in the answer.

Differential Equations, Volume 2:
Section 11 – Linear Homogeneous ODEs with Constant Coefficients:
Complex Root Solutions – Part 2

In this section, we continue to work problems in finding the solution of
homogeneous linear ODEs with constant coefficients and complex roots.
The resulting solutions will have sines and cosines in the answer.

Differential Equations, Volume 2: Lesson 10:
Linear Homogeneous ODEs with Constant Coefficients:
Complex Root Solutions – Part 1

In this section, we continue working examples to balance chemical
equations. The examples gradually increase in complexity such
that we end the section by balancing equations that have several
compounds with polyatomic ions.

Chemistry 1, Vol 2: Lesson 7 –
Writing and Balancing Chemical Reactions – Part 2

I’ve posted a new Chemistry Lesson in the member’s area!

Section 6: Balancing Chemical Reactions

In this section, the student will learn how to properly write a chemical
reaction and balance it. We begin by introducing how to write the
reaction down and discuss reactants, products, and how to keep
track of solids, liquids, gasses, and solutions in the reaction. Then,
we discuss the stoichiometric coefficients and how to balance the
reaction to obey the law of conservation of mass.
