<p>AP Calculus AB
I am practicing free response and the derivations and integrals are a bit tedious. I feel like there's a calculator shortcut I'm missing.
Help!
How should I use a graphing calculator to aid me during the exam?
Can I derive or integrate with this thing?
(I'm familiar with algebraic functions and graphing)</p>
<p>Thank you!</p>
<p>Which version do you have? TI-89?</p>
<p>if you have an 83 or above you should be able to calculate the integral by entering the function into your y value hitting 2ND and then CALC which will brig up options ranging from finding zero’s, to points of intersection, and the definite intergral calculator which for me his number 7. </p>
<p>A little confusing I know, but why didn’t you go over this in your Calc class?</p>
<p>With a ti-84 or 83 go under the MATH menu and use nDeriv( and fnInt(. The format for the two are</p>
<p>fnInt(f(x),x,a,b) to compute the integral of f(x) with respect to x from a to b.</p>
<p>nDeriv(f(x),x,a) to compute the derivative of f(x) with respect to x at the point (a,f(a)).</p>
<p>It’s easier to do with an 89. You just click the green diamond button and look at the number keys…you should see an integral sign or a dx for derivative. You click that, plug in the equation in the field…like so.</p>
<p>dx(x^2+3x-2, x, 1)</p>
<p>That means you’re finding the derivative for x^2+3x-2 in terms of x, and the 1 stands for first derivative. If you wanted the second or third derivative, you’d put a 2 or 3 instead.</p>
