There is a new Student:-ODEs package for working with, plotting, and solving individual ordinary differential equations and systems of ordinary differential equations.

The package includes the following components:

The Student Basics package includes new commands for stepping through arithmetic and algebra problems:

Many other solution steps commands also produce better, more detailed steps in Maple 2021.  See the Solution Steps page for more details.

There's a connection to the new product Maple Learn as well.  This command can output a link to a Maple Learn document containing the solution steps.  Maple Learn is a dynamic online environment for teaching and learning math, focused on high-school to second year university.  For more about Maple Learn, visit https://www.maplesoft.com/products/learn/

By default, Maple does trigonometric computations in radians.  With the new Degrees package and commands for doing the trig functions in degrees, you can now work in degrees instead if you prefer.

These trig functions accept input in degrees instead of radians:  cosd, secd, sind, cotd, tand, cscd

$\mathrm{with}\left(\mathrm{Degrees}\right)\:$

$\mathrm{cosd}\left(90\right)\;$

$\mathrm{sind}\left(90\right)\;$

$\mathrm{sind}\left(400\right)\;$

These inverse trig functions produce output in degrees instead of radians:  arccosd,  arccotd, arccscd, arcsecd, arcsind, arctand​

$\mathrm{arcsind}\left(\mathrm{sind}\left(30\right)\right)\;$

$\mathrm{arccosd}\left(0\right)\;$

$\mathrm{arcsind}\left(-1\right)\;$

Commands in the Degrees package help with conversion back and forth from radians and degrees forms.

$\mathrm{ConvertToDegreeForm}\left(\sin \left(x\right)\right)\;$

$\mathrm{ConvertToRadForm}\left(\right)\;$

After loading the Degrees package, some commands can work directly with the symbolic forms of degrees-based trig functions.  

$\mathrm{solve}\left( \mathrm{cosd}\left(x\right)\, x \right)\;$

$\mathrm{int}\left( \mathrm{sind}\left(x\right)\, x \right)\;$

$\mathrm{diff}\left(-\mathrm{cosd}\left(x\right)\, x \right)\;$

$\mathrm{trigsubs}\left(\mathrm{sind}{\left(x\right)}^2\right)\;$

$\mathrm{trigsubs}\left(\mathrm{sind}\left(180\left(a+b\right)\right)\right)$

$\mathrm{expand}\left(\mathrm{sind}\left(x\+y\right)\right)$

$\mathrm{evalf}\left(\mathrm{sind}\left(12\right)\right)\;$

$\mathrm{Simplify}\left( \sin {\left(x\right)}^2\+\cos {\left(x\right)}^2\right)\;$

$\mathrm{floor}\left(\mathrm{sind}\left(12\right)\right)\;$

$\mathrm{Simplify}\left( \mathrm{floor}\left(\mathrm{sind}\left(12\right)\right) \right)\;$

The SingularValues command has been added to the Student[LinearAlgebra] package. The main difference between this command and LinearAlgebra[SingularValues] is that the use of hardware floats and conjugates have been disabled by default. For example:

To make the student experience more seamless, this Student version of SingularValues is now used for all Student Linear Algebra > Solvers and Forms > Singular Value Decomposition entries in the Context Panel. The Frobenius Form and Smith Form entries have also been removed from the Context Panel for Student Linear Algebra to simplify the options, since they are usually not taught in a first or second course on Linear Algebra. On the other hand, entries for Adjoint, Characteristic Matrix, and Minimal Polynomial have been added to the main Context Panel for (non-Student) Linear Algebra to enhance the options available to more advanced users.
