Write the Trig component form of a vector with magnitude 9 and an angle 45 degrees below the positive x-axis.

Question

Remember to make direction angle between 0 and 360 degrees). Do not write the degree part out. Ex: 4<cos60, sin 60> 

Trig Vector from = ____<cos____, sin_____

Answer 1

The vector is v = 9cos(- 45°)i + 9sin(-45°)j = 9√2/2(i - j)
