Now if we had chosen the other angle, the angle between the F31 and y-axis, and expressed our expressions, components, relative to that angle, then obviously we were going to end up instead of cosine over here, sine of that angle, and similarly instead of sine for the y expression, we are going to end up with the cosine of that angle. Our waiter was a gay man who had a drag show. Knowing these two quantities means that in our coordinate system, through the calculation of these components, lets assume that both of them ends up at positive values, we will get these two vectors as the x and y components of the resultant force.
