could you help me please... √3.cosX – sinX = √3
Hi,
There's a simpler way.
When you don't know where to start, when given , find the modulus, that is and factor it out.
You would then have
Define and
they're both in and are such that
Thus there exists such that and
Hence
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Here, you can find that
So you can divide by 2 on both sides :
Note that and
So your equation is now
That is
Then remember that
