Hi, need help understanding 2 problems.
Give all the solutions to the following problems, answer in radians.
$\displaystyle \sin(3x)=\sqrt{3}/2$
and
$\displaystyle \cos(x-pi/4)=1/\sqrt{2}$
Thanks.
Ahh the question is to answer EXACTLY in radians and I was told it isn't exactly unless you write it like that.
Also the formula + n * 2 * pi I was told to add because n is the number of times it has gone around the circle.
Hope I explained that decently.
But I understand that I shouldn't have addad sin to the solution, thank you, as always I wasn't aware that it mattered.
