3. 5 tan x ° – 6 = 2 ?

edit: Good. I got the question right.

Simply:

* Rearrange for tan x
* Use the fact that the graph of tan x repeats itself every 180 degrees so tan x = tan (x + 180)
4. 5 tan x ° – 6 = 2
5tanx=8
tanx=8/5
you can use a cast diagram to get both the answers
5. Thanks much appreciated you two! It was the only question I didn't get right! Thanks again!
6. You're welcome.
7. Another quick question from 2001 paper 2

Sorry I don't how to do squared numbers and powers on the computer.

Thanks
8. Use ^ as power or put [sup][ /sup] around the number ie 32

Arc length = where r is radius (ie string length) and the angle is in radians
