# Math Help - Component form of a vector

1. ## Component form of a vector

Hi, Im trying to find the component form of a vector obtained by rotating <0,1> through an angle of 2pi/3 radians. Can someone please help me with this problem? Thanks.

2. $\cos\left(\frac{2\pi}{3}\right)\vec{i} + \sin\left(\frac{2\pi}{3}\right)\vec{j}$
