Your assignment is to do any three of the identity proofs from Visions 2, p. 132-5, nbrs 11, 14, 18. All are not the same difficulty, however, so they’re not all worth the same mark. Here’s a table to tell you what each of those questions is worth, if done perfectly:
Now here’s what I mean by “done perfectly”:
- Uploaded to your blog
- Every single step is shown
- Every single step uses proper notation (ie not just “cos”, but “cos x”, and none of this “cos^2x” nastiness – I want to see cos²x!)
- Every single step is explained by identifying the type of identity used and/or the algebra
- The overall form is correct (LHS seperate from RHS, both sides =, QED)
- It is all correct.
So if you do three easy ones perfectly, you’ll get 70% on this assignment. If you do one easy, one medium, and one hard perfectly, you’ll get the same mark as if you did three mediums perfectly.
Here’s an example of one done perfectly (if I do say so myself) in handwriting:
As usual, bonus points are rampant! Use codecogs, paint, Microsoft Equation (that comes with Word/Powerpoint), Mathtype….bring it!
