well

Quick coverage of reason for possible confusion

That nobody told the Physics Department of the Maths changes

See the wave shapes for sine and cosine

How sine and cosine graphs came to be

Revisit yesterday’s lesson to see the sine, cosine and negative sine waves in action

A link between maths and physics

Set a due date for SHM, Units 1, 2 and 3

How to influence our workstream

HW marking + HRT How to stay up-to-date

7 Physics Homework MarkingNo. of marks

What for

1 Having sketches and FULL working

1 Neat presentation and down-page format

1 Answer underlined and units given
