Hi!
I am a freshman in a Geometry class and my teacher is not real big on more in-depth explanations, but when he does, it just complicates everything so much more. I really need help with proofs, for we will need them for the rest of this class and I do not understand the entire concept. I don't know how to word the explanations or what to even put down. Please, if you know how to do proofs, such as the flow-proofs or 2-column-proofs, let me know.....especially if you are really patient and good with instructing people. Thanks!

A particle moves along a straight line with velocity v⁡(t)=t+2 meters/second. Assume that the time t is measured in seconds. Suppose that t[0] .. t[3] divide the interval [2, 8] into 3 equal intervals. Use these subintervals and the right endpoints as sample points to compute a Riemann sum which approximates the distance traveled by the particle for the interval of time [2, 8].
