Page 66, Ex6 – ques. 3 to 8

Today we are learning to … sketch graphs of trig functions.

Sketched graphs of:

1)         y = cos x° + 1                        

2)        y = 2sin x° – 3

3)        y = sin 3x° + 1                      

4)        y = 2 cos 3x° + 1

Today we are learning to … integrate by substitution.

Went over some questions from yesterday.

Started discussing Volumes of Revolution.

Today we are learning to … work out missing angles.

Studied Vertically Opposite (X-angles), Corresponding (F-angles) and Alternate (Z-angles).

We then did some questions from:

Page 19, Ex3A – ques. 2, 5, 6, 8

Page 21, Ex4A – ques. 2, 9, 10, 11

Page 24, Ex5A – ques. 2, 4

Page 25, Ex5A – ques. 7, 8, 11, 12

NOTE:

Today we are learning to … use algebra to write answers.

Page 38, Ex3A – ques. 11, 12

Today we are learning to … work out different types of pay.

Discussed taxes (income tax, VAT, National Insurance, council tax, road tax, duty) and why there are so many in Britain.

Looked at how to use a multiplier to add on a percentage (e.g. to add on 17.5% to £60:   Price with VAT = £60 x 1.175).

Today we are learning to … integrate using a substitution.
