<p>Let's take turns posting formulas and such that are useful but easily forgotten:</p>
<p>If g(x) is the inverse of f(x), g'(x) = </p>
<p>1/
f'(g(x))</p>
<p>Memorizing formulas is never an effective way at understanding the materials. With that said, right now I'm more concerned about wasting 83 than trying to rederive all the formulas.</p>
<p>that inverse f(x) formula u putup is just about completely useless cuz AP will NOT test it on more than 1 mc. as far as relevant but forogtten formulas go:
d/dx arcsinx = 1 / (1-x^2)^.5
d/dx arctanx = 1/ (1 + x^2)</p>
<p>and the integral for the stuff above</p>
<p>I'm having a really hard time processing the BC material (self study BC). What book did you guys use? Barrons/Princeton? I find Barrrons hard to understand.</p>
<p>use princeton. Except for series. Use barrons for that.</p>
