However, what is less clear is that Desmos can also interpret parametric equations as well, provided that we type in the equations for $x$ and $y$ as if they were the coordinates of the points instead (as in $(2\cos t, 3 \sin t)$ ), and that the variable $t$ - the designated variable for parametric equations in Desmos - is used throughout the expression. In fact, implicit functions such as that of a circle, an ellipse or a hyperbola are all very good candidates for this. Since Desmos has its interface in Cartesian coordinates by default, it’s only natural that one would use it to plot equations expressed in terms of $x$ and $y$. In which case, just know that the $\le$ symbol can be obtained by typing out and = , again in that order. In some occasions, it might be necessary to use the $\le$ and $\ge$ symbols to define a function accurately. Note that Line 1 and Line 2 are equivalent. Which should produce the following figure: The sign function.
The same goes other Greek Letters such as $\alpha$, $\beta$, $\tau$ and $\phi$.
Indeed, if at the end of the module you still find the scope of Desmos’ functionalities unappealing, then - and only then - shall we concede defeat and return to our ivory tower for more advanced Buddhist meditation training! On the other hand, if you’re just way too lazy to read the 12-page Desmos user manual, and are looking for more concrete examples to kick-start the creative process, then this one is for you too! Don’t believe in the mighty power of Desmos? Good job! Because it’ll then be our duty to beg to differ, and attempt to convince you otherwise. Instead, it is probably better known as an innocent-looking math tool for the scientifically-minded, making applied math ever more palatable and entertaining! As Greek-mythology-inspired as it sounds, Desmos actually has nothing to do with the giant monster responsible for turning Mount Olympus into rubble through the wrath of infernal flames. And it comes with a funky name as well: Desmos. In particular, there’s a certain education startup out there, relentlessly seeking to hijack our Internet browsers and mobile devices into a - should we say - graphing extravaganza. Sure, while programmable calculators in general are still pretty much popular these days, the graphing calculators from the 21 st-century are also coming in waves as we speak - potentially disrupting the market of scientific computing and educational technology.
Think you’re fond of of graphing and computing stuffs? Great! Because you might remember this thing called the Texas Instrument TI-83 from the old days.
