<p>I was looking over the CollegeBoard rules and it says
"Calculator memory will not be cleared. Students may bring any programs they wish."</p>
<p>I'm just wondering if anyone taking the AB exam tomorrow is using any cool/specific Calc progs? If you have any recommendations please share. Thanks :)</p>
<p>I have a RAM program and a trapezoidal rule program. I think the most useful programs are the built in fnint and nderiv.</p>
<p>Thanks. What is a RAM program?</p>
<p>big<em>al</em>40... dude, I can solve the trapezoidal rule problem faster than plugging in calculator...</p>
<p>how do you actually use the nderiv( function. I know how to use the integral one but I've never used the deriv one. Basically I want to know the correct syntax.</p>
<p>Most of the trapezoid area/RAM approximations are data extrapolated from graphs. It is easier to do the math in one's head than to use a calculator</p>
<p>nderiv(function,variable,point)
Example: nderiv(Y1,x,7)
