Terry Lee's 4unit maths book (1 Viewer)

[RIZAL]

Hi, just wondering whether anyone else uses this book....

To me it is a lot more challenging than other four unit books (especially his set C questions).

Before I got this book I didn't know that resistors resistive force could be displayed as a complex number and I also had no idea what a cardiod was.

The complex resitor bit is uni level electrical engineering (ie don't bother).

A cardiod is a grapph shape (looks simliar to the way telegraph-pole wires hang).

do we have to know either of those two things!?!

Did you read my post? (the one just above yours)

The first one is for un-students doing elctrical engineerin (so no)

The second is interesting but you don't need to know it (there are many interesting graph shapes, ask your teacher about the one shaped like a heart.)

This man has haunted my dreams since i found out about him. I feel my heart tremble just at the sound of the words Terry Lee. That man is just built different.
