In this BL session, you will be covering the following section from Chapter 7: 

• Section 2.2 Solving Differential Equations by Method of Separable Variables

• Section 2.3 Solving Differential Equations Using Substitution

Use the following learning activities to master the key concepts. Rem to fill in your lecture notes as you go along!  

You should take ~50 min to complete this lesson. 

LEARNING (45 MIN)

Please note that these videos use an old version of the lecture notes and syllabus document. In particular, the number of the examples is different. However, the material contained within is still relevant for you. 

PART 1

1. Watch this video and fill in your lecture notes: Lecture Section 2.2 (Solving Differential Equations by Method of Separable Variables).

2. Attempt this Checkpoint Quiz to see if you can identify correctly differential equations that can be solved by the Method of Separable Variable.

PART 2

1. Watch this video and fill in your lecture notes: Lecture Section 2.3 (Using Substitution to Reduce a Differential Equation).

Question to ponder (after watching video): Before applying the given substitution, will I be able to already anticipate which variable(s) would be left in the new differential equation (after the substitution is applied)?
