I'll guess that i and j are supposed to represent unit vectors in the x and y directions. What anges are theta1 and theta2?&nbsp; What about all the numbers? Regardless, there are clear errors in the equations.&nbsp; Note that a simple dimensional analysis indicates that there are problems.&nbsp; For example, the dimension of f is length, but the equation for f has the length parameter (EF) in the denominator.&nbsp; If theta1 is the angle of the beam EF from horizontal then you want</p> <p>&nbsp; f = -EF*(cos(theta1)*i + sin(theta1)*j)</p> <p>There are similar issues with the other equations.</p> <p>It's not at all clear what the various numbers and letters correspond to in the worksheet.
