Find the component form of v if ||v||=2 and the angle it makes with the x-axis is 60 degrees

Let v = (x,y) This then means that x = ||v||*cos(theta) and y = ||v||*sin(theta)
I should point out that v is a vector. The quantities x and y are scalars.
so i put 2 where the ||v|| goes, but where do the degrees come in?
oh and I should have mentioned that theta is the angle
so replace theta with 60

so x=1 and y=1.732
you nailed it
so v = (1,1.732)
well that one was easier than some of the others :)
yes it was, do you see how I got x = ||v||*cos(theta) and y = ||v||*sin(theta) ??
