Today after answering some HW questions from sections 7.7 and 7.6 we started 7.8 Exponential Functions. These are important and have been asked in the Leaving Cert.

All the examples from this section are explained in the video posted here. Please take the time to look at these examples.

HW try questions from 7.8

Today we first corrected HW from sections 7.5 Inequality proofs and 7.6 Indices. We then looked at the examples and a question from 7.7 Exponential equations.

Simple Proof by Contradiction

1/26/2014

0 Comments

 
To prove something by contradiction, we assume that what we want to prove is not true, and then show that the consequences of this are not possible. That is, the consequences contradict either what we have just assumed, or something we already know to be true (or, indeed, both) - we call this a contradiction

The LCHL course requires that students can give an example of proof by contradiction. The example below is as easy as it gets.
