<p>if you dont write units but get the right answer is it wrong or what? i completely forgot units</p>
<p>No, you just won’t get full credit. At most, you’ll lose a point. Don’t freak out about it though.</p>
<p>FUUUUUUUUUUUUUUuuuuuu, I did all of the bike problem right except I misread the axes as saying 1 and not .1 so I had her going 14 miles to school lol. My calculus was all correct at least, hopefully partial credit :(.</p>
<p>OMG same!!! i did the same freeeaking thing, so when i was comparing it at the end i was like oh this is too obvious 1.6 is obviously less than 14…do you think we will get partial credit?</p>
<p>I hope so, I said the exact same thing to myself lol. I was like ***, 14 isn’t even close to 1.6 >.>.</p>
<p>lol. I did the same thing, too. there goes what 4 or 5 points. I guess you receive the other points for showing your work and justification. I hope I still receive a 5 anyway.</p>
<p>My guess is that the scoring rubric that the readers have (it’s a more extensive rubric than the “scoring guidelines” that will eventually show up on AP Central) will have a condition to deduct one point for making the error in part (a) of assuming that the y-axis is counting by 1’s rather than one-tenths, and that you likely would not lose additional points for making the same error in parts (b) and (d) with Caren.</p>
<p>I can’t understand how this problem is solved. </p>
<p>The Anti derivative of x In x dx =</p>
<p>Integration by parts.
Let u = lnx and dv = xdx
Therefore du = (1/x)dx and v = (1/2)x^2
The formula of the integral of udv is equal to uv - (integral)vdu
Plug the terms into the formula, integrate, and simplify.</p>
