Intergating with TI-83 Plus

<p>With the integrate function on the calculator, does anyone know how you find a definite integral? Also, is it possible to find an indefinite integral with the same int( function on the calculator? Thanks.</p>

<p>math 9 gives you
fnint(</p>

<p>fnint((function(thing you want to integrate), x, lower limit, upper limit)</p>

<p>I don't think the TI - 83 Plus has the capability to solve an indefinite integral without a program.</p>

<p>Yea, TI-83 can't handle indefinites. You can, however, use an 89 I believe which definately does indefinites. You'd just leave out the lower and upper bounds.</p>

<p>How do you graph a derivative of a function?</p>

<p>Math 8, Prgm, Vars, 1, 1, x, x)
Assuming Y1=Original Function</p>

<p>IIRC...</p>

<p>For getting the derivative, what does "Pgrm, Vars" do? What would you type if you wanted to find the derivative of (x^2+2x+7) for example? And can you find the derivative of a function without using the graph, and can you do it on an 83 rather than an 89. Thanks for any replies.</p>

<p>you can do both indefinite integration and differentiation on a ti 83:
2nd --> calc
you'll see dy/dx aswell as Sf(x)dx on the menu</p>

<p>Doesn't doing that only let you find the indefinite integral and derivative at a certain point on the graph of the function?</p>

<p>yes .</p>
