<p>That’s very upright of you. </p>
<p>Physics, AP Chem, AP Latin, APUSH, Hon Eng III, AP Calc AB it’ll suck.</p>
<p>Not upright, I’m looking out for myself. My moron friend got caught copying my homework freshman year, it was a pain in the a$$.</p>
<p>Your schedule is harder than mine. Haha. </p>
<p>AP Physics (2 periods)
Calc 3/DiffEq
AP Lit
Spanish 4
AP Stat</p>
<p>You should just take BC calc, taking AB then BC is a waste of time.</p>
<p>My school doesn’t have BC.</p>
<p>someone help me with average velocities. i keep scr3w1ng uppp.</p>
<p>Your school sucks. What will you do senior year?</p>
<p>Are you in AP andrea?</p>
<p>Stats, Anatomy, AP Eng, Latin IV, and something. Gov/Econ is a one year course for graduation, but you can take AP Gov and the one semester of econ can be paired with one semester of psych. So sucky.</p>
<p>I’m tired.</p>
<p>it’s college calculus.</p>
<p>okay - if a ball is thrown into the air with a velocity of 40 ft/s, its height in feet t seconds later is given by y = 40t - 16tsquared. find the average velocity for the time period beginning when t = 2 and lasting</p>
<p>a) .5 seconds
b) .1 seconds</p>
<p>i am trying to find the slope of the secant line…but i get the wrong answer. someone helppppp me.</p>
<p>We have stupid graduation requirements.
Typing for a semester
e-consumerism (filled by AP Econ, luckily)
Foreign Language 1 yr
Biz/Tech/Life studies 1 semester
4 years of gym
4 years of English</p>
<p>Andrea, I’ll work on it.</p>
<p>Haha, gym. That’s so 9th grade.</p>
<p>Andrea, I got</p>
<p>a)52ft/s
b)125.6ft/s</p>
<p>I just used algebra though, so I’m probably missing something.</p>
<p>haha, well, it is supposed to be -32 and -25.6. i got -8 or something.</p>
<p>ihatemylife.</p>
<p>OK, I see how you do it.</p>
<p>Take the derivative of the position function, then find the velocity at the beginning and the end and take the average.</p>
<p>so P=40t-16t^2, V=40-32t</p>
<p>V(2)=-24<br>
V(2.5)=-40</p>
<p>(-24-40)/2=-32</p>
<p>V(2.1)=-27.2</p>
<p>(-27.2-24)/2=-25.6</p>
<p>i don’t know what a derivative is.</p>
<p>fsaklfjalsdjfasdhflads.</p>
<p>Did this calc class just start or something? Derivatives are like the second thing you learn.</p>
<p>yeah, it just started. this is unit one.</p>
<p>OK, here’s a summary of the basics. A derivative calculates the slope at each value of x. So if your equation is Y=4x, then at each x value the slope will be 4, and the derivative will be y=4. If the equation is y=x^2, the slope is different at each x value, and you have to use chain rule to determine the derivative.</p>
<p>Chain rule</p>
<p>Y=x^n</p>
<p>dy/dx(derivative)=nx^(n-1)</p>
<p>That’s how I got 40-32t from 40t-16t^2.</p>
<p>That’s the best I can explain it. It gets much more complicated, but this is the starting point.</p>
<p>thanks. i am rereading the stuff now.</p>
<p>funny stuff…</p>
<p>don’t make fun of meee. haha.</p>
<p>why not?</p>
