<p>I’m in dire trouble, a consistent theme of mines in mathematics course is to make silly mistakes on exams, quizzes, homework etc. Well at my old university, I could get away with it, because obvious you know how to do the problem and show so in your work, you’d get most of the points here is just one example.</p>
<p>Question Find the exact value of cos theta in standard postion and the terminal side of theta is in Quadrant II and on the line 4x+3y=0 here is my work 4x+3y =0 -4x, 3y=-4x, 3y/3 = -4x/3, y=-4/3 hence tan theta = -4/3 </p>
<p>I drew the 90 degree triangle, my opposite was -4, my adjacent was 3, I used pathagorean theorem to get my hypotenuse which is 5. I did everything right, I even adjusted cos theta to be negative because cos is negative in quadrant II, I simply did opposite/hypot. instead of adj/hypot so instead of
-3/5 I did -4/5. In most math classes you’d get majority of the points for showing you understand the concepts made a simple mistake. Being multiple choice I didn’t get anything. One problem I marked the wrong answer on the scantron. Another problem I was in degree mode on my calculator, I had one other real silly mistake also. So in total those cost me 4 points. The test is only 15 questions so 4 points is nearly 1/3 the test; would have put me near a B, but I ended up failing. I’ve tried and tried and tried, but I can’t catch my mistakes. I’m going to fail if I don’t do something. What can I do?</p>
