[Random Variable]

d²/dx²(?x*e^(t^2)dt from 0 to x)

It took my awhile to figure out what to do first.

This is why your dear and fluffy lord invented TI-89s.

Finding the derivative isn't tricky at all, it's taking the integral first. Pain in the ass is all

QFT.

Personally I prefer Mathematica since it is considerably more powerfull in the range of operations it can perform. Thank god all the advanced classes let you use computers or calculators to solve the math instead of making you do it by hand. In real life at your work you will NEVER solve a single integral or derivitive, so learning these skills is only usefull to gain an understanding of the concept.

If you first use the Euler identity, and then do Taylor expansion, and finally use the L'hospital rule. This should give you the answer of absolutely nothing.

indeed... buy one...

NOW!

buy two even.

 

[Fenixgoon]

so what's the integral of e^(t^2)?

e^(t^2) doesn't have a antiderivative

What's the deal with a TI-89? What's it have that a TI-86 doesn't? Is it THAT much better?

It has the amazing ability to not be able to be used on most exams.

You shouldn't need it on most exams.

Some calc says otherwise.

No, your professor who writes the exam determines that.

So it's a $150 dust collector?

I guess I don't feel so stupid anymore. The easiet approach is to first apply the product rule and then use the fundamental theorem of calculus to find the first derivative.

I guess most people don't really understand the FTC.

Why, because no one cared about your question?

So you don't know how to do it either?

 

[DrPizza]

got here a little late, but I could do that one in my head.. Fundamental theorem of calculus, part II makes it quite simple; after that, it's just one simple derivative.

Pie

it will do text based solving...

if you have a calculus/algrebra problem with only variables... it can still solve it

 

[Accipiter22]

maybe this will help
