<p>Complex analysis, anyone? The thread is ripe for a mathematical conversation.</p>
<p>^Once I get into AP Calculus, which is next year, then I’ll be GLAD to talk about all this mathematical stuff.</p>
<p>In the meantime, one of my older friends was teaching me about derivatives, which seemed really easy, but then she had to leave, so I didn’t get the whole lesson. Do you know of any website that could teach me thoroughly?
Idk why, I just want to learn it before the actual class starts.</p>
<p>Let f(z) be a function of a complex variable (z=u+vi). Then
f(z) = x(u,v) + i<em>y(u,v)
df/dz = d/du ( x(u,v) + i</em>y(u,v) ) (the partial derivative with respect to u)
by the Cauchy-Riemann conditions.</p>

I find them very helpful.</p>
<p>Thanks man! I’ve already learned quite a bit.</p>
<p>5 on Cal BC (Wednesday May 8, 2013) beyond the shadow of a doubt</p>
<p>it should be just as easy for you all</p>

Do you think you did well? In responding, let’s not discuss the actual test questions.</p>
<p>It was really easy. We can discuss frqs though.</p>
<p>@Secoja8 I got a 1560 (excluding writing) but my dad wants me to go for 1600.</p>
<p>I will be taking AP Calc BC next year as a sophomore. I will however be learning most of the material over the summer (as I am somewhat familiar with it) so that the class is a breeze.</p>
<p>I feel like I’m the least advanced here.</p>
<p>I’m not even in Calc.</p>
<p>Yeah, I got an 800 on Math Level 2!!! :)</p>
<p>Can you miss 5 questions and still manage an 800 on the Math 2 subject test?</p>
<p>Yeah for sure. I definitely got at least 5 wrong on the test, and I got an 800.</p>
<p>York: Yes, in fact, you can miss six and still get an 800.</p>
<p>We have a club? This is a thing?</p>
<p>Interesting math article:
[Fractional</a> Calculus](<a href=“http://mathpages.com/home/kmath616/kmath616.htm]Fractional”>http://mathpages.com/home/kmath616/kmath616.htm)
With a basic understanding of calculus and induction, this should be fairly understandable.</p>
<p>MVC, Diff Eq, freshman, college.</p>
<p>Yay, when I actually get to USE this math. When the prerequisites are math classes ;D</p>
<p>I think I win by some. Next year will be MVC and Diff eq as well (plus maybe one or two other maths if I want more) and I’ll be a junior in high school. One of the classes I’m most awaiting is when I’m a senior I’m planning to have a MVC based chemistry class and seeing a math rigorous science course sounds interesting to me.</p>
<p>Here’s something interesting:
The solution to the first order differential equation in the form (f is a function of x and y)
df/dx + (df/dy) dy/dx = 0
is
f(x,y) = c
The above equation is called an exact differential equation.
If you look closely, the left side of the first equation is a multivariable chain rule (f’(x,y(x)))</p>
<p>One more thing… sorry for bumping
Out of your schools, how many students took calculus in 10th or sooner (including yourself) out of how many students at the school?</p>
<p>Mine:
2 students out of about 2000 students total (9th-12th)</p>
<p>Is the ratio higher for y’all?</p>
