I am having trouble understanding when to use sine and cosine to find x and y components. I know that its not always going to be the same (ex. you won't always use cosine to find x component.) Any input would be appreciated!
Yea I always draw a diagram but if you draw out those angles and vectors some of the require sine to find x-component and 1 requires cosine because its in another quadrant.yeah! draw a diagram
but since all angles are measured from +ve x-axis anyway, things are so easy that you just plug in the angle: cos for x-comp, sin for y-comp. what do u mean by they don't match up??
