Preparing for next year 6
Hi,

I've asked for a list of questions from a teacher to do over the holidays. I'm struggling to use the text book to help me.

Could someone provide HOW to do these questions, as I just want to get an idea of what I'm getting next year.

Thanks.

An equation of this form is only going to have a nice solution if:

$\cos(x)=\sqrt{3}\sin(x)$

and as the equaltion has only one root in the given interval this will give "the" solution
