Find the component form of a vector v given the magnitude of u and u+v and the angles that u and u+v make with the positive x-axis.
sorry, fixed.....
||u||=2, $\displaystyle \theta$ = 230, ||u+v|| = 8 $\displaystyle \theta$ = 80
I can't find any problem like this in the book, instructor gave us this as a take home problem to work on.... (Thinking)
