Question

tan13pi/4

A. Use the fact that there are 2pi radians in each circle to find another angle, smaller than 2 pi, that is equivalent to 13pi/4.

B. Find the tangent of the angle you found in part A. This is also 13pi/4.

Answer 1

hint:
the x-component of the vector is four units long, whereas the y-component is one unit long, so we can write this_
\[\huge {v_x} = + 4,\quad {v_y} = + 1\]
