<p>It's calc. It says:</p>
<p>A ship is moving away from shore at a speed of 30 knots and a person on the ship is moving toward the bow at a speed of 3 knots.
a- How fast is the person moving from the shore?
b- What rule of differentiation does this show- power, sum, difference, product, or quotient?</p>
<p>Is it 33, sum or how do I do this?</p>
<p>ideas on this?</p>
<p>Yup! Wow, it is a bad question. But it demonstrates the sum rule (the derivative of a sum is the sum of the derivatives). ie. if the the center of the boat's distance from the shore is A, the guy's distance from the center of the boat is B, and the guy's distance from the shore is C:</p>
<p>C=A+B
dC/dt = dA/dt + dB/dt (DUH!)</p>
<p>It's from a worksheet he gave us and many of the other questions are complex, but I looked at that and was just like, wait a minute, am I overthinking this one? Ok, but thanks.</p>
<p>you;re still on derivatives?</p>
<p>lol yes, it's block scheduling. we just started class the beginning of february. we start integrals after midterms, like the second or so week of april.</p>
<p>taking the AP exam?</p>
<p>No one from our class of 30 is but he offered to sit with us and work ahead with any of us if we wanted to but no one EVER has taken any AP exam at my school except like 3 for english and 1 for bio last year because we get dual credit..yada yada
I think if people took the exam, it would be first semester class.,</p>
<p>Wow, you must go to a ********* school. Are you applying big?</p>
<p>Yes I am...sort of...Cornell and NYU the highest. I actually agree with it though. I would not stand a class that is focused on learning how to do well on the exam rather than learning a subject. Plus, many schools don't even accept exam credit so it's a waste of money, time, and effort. Our principal is totally against ETS. We only have the SAT at our school twice a year and she refuses to allow SAT IIs in our school, so I have to go to another school for those. But she thinks ETS a scam.</p>
<p>Wow, thats a little harsh isnt it. Sounds like a totalitarian regime to me. But Im glad youre applying big- way to be a rebel! (And a smart one at that!) ;)</p>
<p>With that said, if I eve attempted the AP Calc exam, I would be lucky getting a 3 because my teacher likes to overly simplify things as my question above shows. He also doesn't make us memorize a ton of stuff that the AP would have.</p>
<p>There's not too much to memorize. Not any more than the other AP exams.</p>
<p>I know but still I don't know. He grades so easy. He'll give us 15 question tests and only take off like 4 points for wrong answers. (4 pts. off 100) 15*4=60...so if we get every single one wrong, we get a 40, I have a 97 average but I don't think I'd be able to handle it since we never discussed what its even like, so it would be a waste of money.. and my parents would make ME pay all of it.</p>
<p>Yeah, that sounds a lot like my AP Literature teacher. She hasnt given us
a single practice test yet, and half of the class has a 100 in the class. On the other hand, my AP Chem teacher is really hard on us and I think my class is well prepared for that one.</p>
