That kinda makes sense lol. Still confuses me
Heres one for anyone to have a go at...

Solve the equation sin (x) = square root of 3 cos (x) for x (wierd symbol that i think means all elements of ) [- pie , pie], giving exact values in terms of pie
--- End quote ---


Divide both sides by cos(x) and you get....
tan(x)=square root 3
x = -2pi/3 and pi/3

EDIT:

Ah, too late

But exact values are very important for the exam, so you should learn them

Ohh yehhh damn I should know that :@
