Calculator

I am looking to get a calculator that can do symbolic integration and differentiation. E.g. If I put in the integral of (sin2x) it will give me -0.5cosx

What is the best (preferably cheap!) calculator that can do this?

Btw I know these are not allowed in UK exams..
No idea but what's the point.

Outside your exam you could just use Wolfram Alpha.

Can't go wrong with the good old Casio in my opinion :wink:

Agree with Mr M, what would you actually want to achieve from this? (other than throwing ~£200 down the drain) :tongue:

You can get Casio ones which will differentiate and integrate for you for about 15 quid.

Edit: Just found it... http://www.amazon.co.uk/Casio-FX-991ESPLUS-SA-UH-FX-991ESPLUS-Scientific-Calculator/dp/B0034BAQS8/ref=sr_1_3?ie=UTF8&qid=1364336888&sr=8-3 I think it does the job but I can't be too sure if it will do it with unknown values.

The calculator that produces his answer presumably would be cheaper than £200 ... ?

Not symbolically.

I was more referring to the fact that ∫sin2xdx=−12cos2x+C\displaystyle\int sin2x dx = -\frac{1}{2} cos2x + \mathcal{C} rather than −12cosx+C-\frac{1}{2}cosx + \mathcal{C} but yes, I suppose the + C as well :tongue:

Did I get the wrong end of the stick? :colondollar:

I didn't even notice the missing 2! :mad:

Yes - your point was valid too though!

Sorry for the late reply. The reason I want to buy one is because my college has given me a £100 bursary to spend on books (I was meant to get this payment in September) but I have already got all the books I need. So they said I can buy a calculator with the money.. Hence why I am asking for a good calculator to buy..

Could you buy software instead? Purchase a student copy of Autograph or some such?
