The Casio ClasszWiz took approximately a minute to solve it. Its processor is a little faster than the 36XPRO but it is amazing these 2 inexpensive calculators can do this. As far as the Prime I heard that one F16 pilot said his cockpit wasn’t as complicated as the HP’s most capable calculator. Great machine but a little too complicated for its own good.
Thanks again for inspiring the video, I.C. Yes, Prime is amazingly powerful, but overkill for what I typically need and not as easy to use as I would prefer.
I can verify that this problem can be solved on the Casio fx-CG50 and fx-9750GIII/9860GIII through the Equation-Solver application in a relatively short amount of time.
GeoCal, that never occurred to me! Good thinking. It's a little strange using x both as a constant (for the upper bound of the integration) and as a variable in the expression, but if it works, it works. Thanks for the tip.
I am still really impressed that a $20 calculator can do this. Glad you left a comment and good reminder that the results are auto-stored in the x variable.
I also tried this on the TI-nspire cx cas and I think it almost broke the machine. It kept on going with a clock on the screen continuously moving. I couldn’t shut it off or break the solve sequence. I guess I will just have to let the battery run out.
Funny (and sad). It seems like a calculator of that price point and power should be able to out-perform the lowly (?) CASIO fx-991EX. I did finally get the Prime to work and it is FAST (1 second or less) -- but, somewhat buggy in terms of input/parsing -- I would not have figured it out without @C Ret's comment below. I plan to make a short video at some point showing the Prime solving it.
GOOD question. I had the same thought. At this point "I do not know." is the answer. I may look into this at some point -- I'm confident that a program could be written to iteratively solve it, but that would be a pain. I am curious if there is a clever way to take advantage of the built in iterative solver to solve this sort of equation.
@@scottcollins7513 I just recently received my DM42, so needless to say I am a newbie still learning it. But on the solver I am wondering if a program is always needed or if it can be used with some ov the calculators built in functions.
@@jeffreyfleek8655 The thing that has me skeptical about getting DM42 to do it without a custom program is the fact that I doubt we can "nest" the definite integral "solver" within the numeric solver itself. I'm not optimistic. I am also, admittedly, not a power-user of the DM42 -- it is my favorite daily driver, and I have created some custom programs for it, but nothing too complicated. Perhaps some DM42 power-user might chime in on your original question...
@@scottcollins7513 Just a follow-up, but I guess it's time for you to make a video about solving these types of problems on the DM42. Maybe this will encourage SwissMicros to address these issues with a "num-solv" function.
@@JohnUsp 2 years ago I said what I still think now. I'm guessing there is an algorithm for iteratively solving this sort of problem (i.e. NOT using knowledge of anti-derivative, etc.) using successively smaller and smaller "slices" to find the area under the curve. I'm not sure it is something I want to invest time into when it is not the type of problem I would try to solve w/ the DM42. Who knows, maybe I will feel more inspired at some point. At any rate, I appreciate you following up on this as I had forgotten all about it.
My HP 48sx did it. My Ti-36X Pro did it. My fx-991 ES Plus C did not do it. My fx-991EX did it. My fx-9750giii did it. My CG-50 did it. HP Prime G2 did it, instantly!

Ti 30 x pro ( new version of 36x pro) Mathprint took a little less than 14 seconds without the guess

Good to know, Edward. Thanks for the info.
Wow, I would never think it could do that.
Agreed! Rather amazing. Thanks for leaving a comment.
3:10 Scotty, why didn’t you simply key in the “x” variable to the upper bound that you just solved for?

Thank you. The result "4.1841...." was stored on "x" variable.

Can the dm42 do it?

Very useful, thanks.
How did you do that on "Casio CG-50"? Mine is running forever. Thanks,
My hp50 solves it after 2 minutes!
Slower than I would have expected, but still beats the TI-36X Pro by a good margin. Thanks for the info.
