I notice when attempting to calculate the integral from 0 to infinity of something like e^(-x), the calculator starts giving incorrect results when you increase the upper integral bound above 3563 (result should be 1 but at upper bound of 3564, but instead we see .000009968).<br /><br />Great calculator though, I use it over my TI-89 all the time because they really did a good job making the things that are useful very accessible. liquidifyhttp://www.blogger.com/profile/08508090008162044063noreply@blogger.comtag:blogger.com,1999:blog-9169922911599301079.post-38206812509647358732017-03-14T06:08:29.300-07:002017-03-14T06:08:29.300-07:00Yes - it is a calculator worth checking out.

The closest thing I can think of, is to use a stored operation as a formula in x or a. <br /><br />op=sin(x) [ or other function ]<br /><br />Store the argument in x and run the op as such: 1 [op]. It is interpreted as 1 * [ f(x) ]. I tested this on a TI-34II but I would imagine the TI-36X Pro would handle this just fine.<br /><br />EddieEdward Shorehttp://www.blogger.com/profile/13278913865743064653noreply@blogger.comtag:blogger.com,1999:blog-9169922911599301079.post-13223185032347228062017-01-26T13:28:01.401-08:002017-01-26T13:28:01.401-08:00Been playing with stored operations.

Love, love, love it. <br /><br />Advice to potential engineers: buy and use the calculator you are more familiar with. you have enough to learn and you dont need to complicate it with trying to learn how a new calculator works. If you aren't familiar with ANY of them, then it doesn't matter what you pick. For what it's worth, ppi2pass likes the casio FX 115ES. I'm more comfortable with TI so that's what i used.<br /><br />As for the % issue. All of you purists are right - the % key "works" perfectly, exactly as designed - it correctly divides by 100 - cosmic. Hit your start button, type in 'calc' and fire up the old windows calculator. Now type 21.99 + 9.75% and enjoy the result of 24.134025. Wasn't that easier? Don't you now wish your calculator did that? I guess i wish i could toggle that behavior somehow...weowhttp://www.blogger.com/profile/07697169672062163524noreply@blogger.comtag:blogger.com,1999:blog-9169922911599301079.post-32958537477318986612015-06-15T16:10:44.169-07:002015-06-15T16:10:44.169-07:00"typing 21.99 + 9.75% returns 22.0875, not 24..."typing 21.99 + 9.75% returns 22.0875, not 24.134025 (what it should be)."<br />To do this, you type [ 21.99 * 109.75% ].

One problem that we can run into if we tried to use the TI-36X Pro is that the battery allows for data to be stored in the calculator after the calculator is turned off. <br /><br />To contrast, the classical TI solar calculators (30-STAT+, 36X to name two) do not have battery back up. Each time the calculator was turned off or the calculator was removed from a light source, the entire contents of memory were cleared. <br /><br />Eddie Edward Shorehttp://www.blogger.com/profile/13278913865743064653noreply@blogger.comtag:blogger.com,1999:blog-9169922911599301079.post-24650490126408131212015-02-10T09:07:46.204-08:002015-02-10T09:07:46.204-08:00Hi Eddie,

If the battery (CR2032) was taken out from this calculator, will it still work properly if there was enough strong light shining on its solar panel???<br /><br />Also, I noticed there are some differences between this and TI-68:<br /><br />1) The polynomial equation solver for TI-68 can solve equations of degrees 2-4; the TI-36X pro only degrees 2-3.<br />2) The simultaneous equation solver for TI-68 can solve 2 - 5 equations, while the TI-36X pro only 2 - 3 equations of this type.<br />3) On the TI-68, there is a delta % function, where it works out the difference between two numbers in %. I don't think the TI-36X pro has one.<br /><br />Please answer me if the TI-36X pro can be powered up (without battery) by sunlight/strong indoor light, thanks.<br /><br />JohnJohn Liuhttp://www.blogger.com/profile/17408255241838184064noreply@blogger.comtag:blogger.com,1999:blog-9169922911599301079.post-79756874111915295272014-12-08T16:24:44.832-08:002014-12-08T16:24:44.832-08:00But, Eddie, the Casio loses all of your work when ...But, Eddie, the Casio loses all of your work when it times-out and powers-off; a complete failure in an advanced scientific calculator; the TI retains your work.Lonewolf™http://www.blogger.com/profile/17592367417704960634noreply@blogger.comtag:blogger.com,1999:blog-9169922911599301079.post-38401016144471355552014-11-08T14:55:22.729-08:002014-11-08T14:55:22.729-08:00Cannon F-792SGA would definitely qualify as a four...Cannon F-792SGA would definitely qualify as a fourth option.<br /><br />Edward Shorehttp://www.blogger.com/profile/13278913865743064653noreply@blogger.comtag:blogger.com,1999:blog-9169922911599301079.post-51618400794706135912014-11-08T14:54:03.983-08:002014-11-08T14:54:03.983-08:00I think because the fx-115ES had the better keyboa...I think because the fx-115ES had the better keyboard and it has a larger constant/conversion library.
