If an converges to 0, then 

Write the equation of the line that is normal to the plane x – 3y + 4z = 19 and passes through the point (6, -2, 3). 

To the nearest degree, find the angle between the vectors: v = -i + 3j + [a]k w = 2i + [b]j + 4k

Write the equation of the plane that contains the points P(0, 0, 0), Q(1, 2, 3), and R(2, 1, [a]).  Write your final answer in the form ax + by + cz = d.     

Part One: Material from Exam #1 For multiple choice, T/F, and fill in the blank questions, please answer accordingly. For free response, please work your problem on your scratch paper.     

If an does not converge to 0, then 

Write the equation of the line that is normal to the plane 4x – y + 3z = 19 and passes through the point (5, 3, -1).
