one more chance left

My homework is due on a website called webassign. If you tell this website to anyone in physics usually they curse and scream and throw things at the computer. There are several things about the program that is a good thing like there is a bit of a rounding error factor that is programed in and also there is 5 chances to get the right answer. BUT there is no partial credit given for work that is half right but you get the wrong answer. After I answer questions 3 times wrong I pull my "Endrit has a master's and should know this stuff" card. So today Endrit had to help me on one question out of 14. He calculated it and I put in the answer in hope...Wrong...only one more chance to give the right answer. He noticed that he missed one sine(theta) in the denominator and recalculated. The answer was different in the way that we thought it would be and with all faith put in that answer. Green check!!! It was right! I was so excited! I try not to pull the "Endrit" card but today this saved me. I am horrible at algebra especially when there is a whole bunch of sines and cosines. I just don't register these things in my brain. I have gotten good points on my tests with setting up the problems and not so good on the algebra. It is crazy! Oh well. All I can do is practice and hope that I learn how to do algebra. I got an A in Trigonometry, and a C in College Algebra...my mind doesn't work that way. Wish me luck.
