# Math Help - component form of a vector

1. ## component form of a vector

Need to know how to solve this. Find component form of v if ||v||=6 and the angle it makes with the x-axis is 150 degrees. I understand that the magnitude is 6, but there are many combinations that could end up being a 6. can't I find v with 6(cos150, sin150)??

6(cos150, sin150) is the answer (assuming the angle is measured from the positive x-axis). What is your problem with this ......?
