1. The problem statement, all variables and given/known data My text book shows a vector B 130° from the positive x-axis. B has a value of 5; it asks for the x and y components for B. But they show a way other than SOH CAH TOA. They got the x component by multiplying 5(cos130°) and the y component by multiplying 5(sin130°). What is this method? 2. Relevant equations All I know is SOH CAH TOA, but that obviously will not work in this case. 3. The attempt at a solution I can easily figure it out by putting B into a right triangle to get the x and y components. But I am interested in learning this technique too which I apparently missed some where along the way.
