Findthe mighty power of Desmos appealing and intend to use itextensively in the near future? Answer. To get it started, heres a list of inequalities you can tryout andget the juice flowing: And heres what happened when we throw inthese inequalities into Desmos. However, what is less clear is that Desmos can also interpret parametric equationsas well, provided that we type inthe equations for $x$ and $y$as if they werethe coordinates of thepoints 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. \] Ceiling function. Alternatively, if we are givena function $f$ and weare interestedin making a more accurate estimationfor the coordinates of akey points (e.g., root finding), we can always try typing in $f(a)$ in a new line and activate the slider for $a$, which in turn allows usto control the value of $a$ manually, and see its effect on $f$ in real-time. (for the record, a new variable doesnt includeany of the pre-defined variablessuch as $x$ and $y$. And if the point is meant to be moving along a circular path instead, putting an expression such as $(3\cos a 5, 3\sin a + 6)$ into the command line would do. Alternatively, wecan alsoevaluate the product of a sequence using the prod command, and if needed stack up as many summations and products as we like.
