Welcome to the eternal math thread. Ask un/important questions and discuss in/famous mathematicians, their work, and mathematics in general hereWord problems are welcome too; if you find the solution to a problem, please be kind and [spoiler]spoiler[/spoiler] your answer
This has been bothering me; what family of functions fits this bill? Boundary conditions are listed below: genuinely do not care about the behavior for negative `t`, and simplicity is preferred since this will be an on-the-fly computationIf it happens that the fn is not particularly simple, I'll use a piecewise function with a linear approximation, s.t.1.) For 02.) 0 Otherwise
This is the approximate curve (though this specific curve is too steep for our purpose). Pulled this from an explanation of the voltage transfer characteristic of a CMOS inverter but I cannot find any hints about the function family. . . there are only paragraphs and paragraphs about calculating specific parameters: typical EE but it's a start nonethelesshttps://courseware.ee.calpoly.edu/~dbraun/courses/ee307/F02/02_Shelley/Section2_BasilShelley.htmThanks 302
>>7029https://en.wikipedia.org/wiki/Half-normal_distribution
>>7030 EDIT: a cool thing i forgot to mention is the half-normal is defined only with the standard deviation, since the mean is a scalar multiple of the standard deviation for this distribution. You could also say the standard deviation is a scalar multiple of the mean.
>>7031Note that this dist is only what you're looking for with a specific value of sigma (sqrt(2/pi))Just because you specified a y-intercept of 1.
>>7030This looks like exactly what I'm looking for, 39The original problem was: I wanted something to indicate wi-fi latency measured in miliseconds. A bar would be drawn / colored in to be a certain percentage of its width depending on your ping (lower ping gets a fuller bar), and I wanted it to look relatively full until about 400ms, then be a lot more sensitive to small changes
>>7033Though actually I guess you could use any value and just scale the response since you're not actually worried about it being a valid pdf
I managed to solve this problem by completely avoiding it
today i managed to solve a problem by completely avoiding part of it. part of an output file had the number along with uncertainty on the same line, so it would be like "5.3010E-3 .002 and i managed to do a 'replace all' on "E-3 ." to avoid writing any sort of script
>>7284Anything to dodge extra work
>>7284 UPDATE: i figured out you can truncate excel values by =left(cell,N) where N is the number of digits to include. Also re-ran the simulation with 1e6 replications instead of 1e4 and used 6 of my cores and my computer became a space heater for 3 hours.
are general questions okaymy instructor dropped mathematica on us and gave no real explanation on how to use itany good resources that aren't a 10-hour youtube series?
>>7461yeause MATLAB or Maple instead
>>7462 we gotta use mathematica tholike im fine with using it, he literally has only offered "the TA made a tutorial on youtube" and it's just an 8-minute video of him telling you what a variable isi just need simple explanation of its workings
>>7463as a math TA I feel bad for himI'm constantly bugged about shit like maple, matlab, and mathematica when I'm a mediocre coder myselfwhat class is this for?doesn't seem like it would be a calc sequence class
>>7465 PY 201 lmao
>>7466oh lolphysics is death
>>7467 the sad part is i've taken an equivalent course before but this is just kind of sillythere is ONE other "resource" for it on moodle but it's deadass just a link to Lynda's homepage
yo fuck calc 2
>>7469 calc 3 is easy, just look forward to that
Take MA225 "Foundations of Advanced Mathematics"Like, if you get the choiceI think it's requisite for MA majors and only suggested for math minors>>7469calc 2 is a rite of passage
>>7472 225 is required for math minors, I took that to fulfill a requirement for my math minor
>>7540https://oucc.dasa.ncsu.edu/mathematics-17mam/>Required Courses> None. MA 225 is not required for the Minor.
MATLAB AAAA
