Now, if you’re doing it for real, the best and also most common method is simply, “use a computer”. Many computer systems are really, really good at solving these equations and inequalities. You can also graph it and see on the graph every time it crosses zero. You can even do it for free without fancy software. There are a lot of web calculators that can do it, but one options is using wolframalpha.com.

Do not go for a “one-use” calculator… Go for something that does it all if you know what you’re doing. Go to wolframalpha.com.

Some context:

– Each “Card” you see is a reference to a block inside a big page called “Remarkable distributions”. That page also contains more details (proofs, notable properties, …) about each distribution.

– The plots are generated using wolframalpha.com. I can just type “normal distribution” and I get a nice plot with different variations of the distribution’s parameters.

Wolfram Alpha is a free website http://wolframalpha.com where you enter text or a formula and the website gives you what it thinks is the best response. It’s great at doing calculations, solving equations, and looking up data (e.g., “speed of light in inches per millisecond”).

The goal of this post is just to encourage us to consider the possibility of these as base-36 numbers. You can use https://wolframalpha.com to convert base-36 to other bases, just type in ff_36 for example to see the result of treating ff as a base-36 value.

I like to use Wolframalpha when I need to see probability curves (if that’s what you’re asking). Enter in “1d6” or “3d6” and you can see how one die has a linear distribution of results whereas multiple dice have a curved distribution. Basically each result on only one die all have an equal chance. Multiple dice means that there are results that will happen a lot more than others.

There’s /r/domyhomework but it’s not free. wolframalpha.com is a nice automated way to solve some problems, and brainly.com (and many other sites) offer free human help.

If you mean in general, wolframalpha.com when I want to know what the schwarzschild radius of a black hole with the mass of the observable matter in the universe is, or anything with units. If the units don’t cancel I at least know my math was shit.

Do you think being able to write things in plain english would help? Some CAS have some support for that. On https://wolframalpha.com/ for example you can write “three times x squared plus five x plus one equals zero” and it will convert to 3×2 + 5x + 1 = 0 and plot and find roots for you.

Normal ISS comm is routed through two geosync comsats to a ground station at White Sands, then to Houston. For the sats to have good line-of-sight to White Sands they need to be positioned not exactly opposite each other, leaving a ‘zone of exclusion [‘ZOE’] over the India longitudes [opposite White Sands]. Check the times of loss-of-signal with the ISS orbital position [use wolframalpha.com for a map]. The idea…
