The 2 Methods to Solve Exponential Equations

There are two methods to solve exponential equations:

  1. Take ln on both sides 
  2. Substitution 

Students must know which method to use when solving an equation. Generally, we take ln on both sides when there is just a single exponential function and we use substitution when there is a common term.

Let's take a look at the examples:

O level A-Math: Collection of Differentiation Tips

Usually at this period, many Additional Mathematics students would be 'sweating' over the rather foreign topic, Differentiation (part of calculus).

Today I have decided to gather all the tips I have written on Differentiation to be on this post so that they are easily accessible for you. Let's take a look what have been discussed so far:

  1. Differentiation Basic Techniques
  2. Stationary points (Includes a video on the step by step solution)
  3. Differentiation involving exponential

So, how have you found Differentiation so far? Easy? Tough?I would love to hear from you on your learning experience so far.

In my coaching programme, I relate Differentiation to Freezing. Do you know why? Well, there is one common property both shared: Decrease.
