Any chance to have "Evaluate->Remove Output From Worksheet" become active and usable when one is still running something in the worksheet?  May be in 2023 version?

This is something that has been missing in Maple for ages.

Maple definitely slows down when the worksheet becomes full of output (from print messages) when a command has been running for long time. Now there is no way to remove the output in the worksheet until the command completes which can take hours. May be this slow down because the scrolling/writing to the worksheet slows down, and this affects how long it takes to complete as the engine is waiting for the frontend to finish writing to the worksheet?. I do not know. I just know Maple slows down when this happens.

I do not understand why Maple can't implement this. Is there a tehnical reson which will make removing current output in the worksheet not possible while a command is running?

We have just released the 2022.2 updates for Maple and MapleSim. These updates are freely available to all customers who have the 2022 version of these products.

Maple 2022.2 includes improvements to worksheet performance, the math engine, and more. As always, we recommend that all Maple 2022 users install this update. It is available through Tools>Check for Updates in Maple, and is also available from our website on the  Maple 2022.2 download page, where you can also find more details.

The MapleSim 2022.2 family of products offers an enhanced user experience through an expansion of the modeling libraries, a range of new productivity features, and several new options requested by users. See the MapleSim 2022.2 update page for details on new features, and for instruction on how to obtain your update.

Physics is a very diverse field with a vast array of different branches to focus on. One of the most interesting areas of physics is optics - the study of light.

It's common to think of light as some super-fast form of matter that just bounces around at 300,000 km/s and never slows down. However, light can actually slow down when it moves through different substances. Imagine dropping a baseball from the air into a deep pool of water. It would slow down, right? Well, what happens for light isn't too different.

We call the air or the water in the previous example 'mediums' (or media). Light moves through each of these mediums differently. For example, light moves close to the speed of light in vacuum, 299 792 458 m/s, in air, but it moves considerably slower in water, closer to 225 000 000 m/s. Take a look at Indices of Refraction for more details on how we can quantify this change in speed and Dispersion for some information on the role that the wavelength of light plays.

So light slows down when it enters a medium with a higher refractive index. It also speeds up when it moves from a higher refractive index to a lower one. But did you know that it also bends? Unlike in the example of the baseball falling into the pool, light that changes speeds moving between mediums will also change direction.

Snell's Law is our way of determining how much light bends between mediums. Try playing around with the values of the indices of refraction and the incident angle and see what effect that has on the refracted ray. Is there a combination of parameters for which the refracted ray disappears? The answer can be found in Critical Angle and Total Internal Reflection.

Welcome back to another Maple Learn blog post! We know it is midterm season, and we’re here to help. Maple Learn can be used to study in many different ways, and I’m sure you’ve already tried some of them. One way is making your notes in Learn, or making your own examples, but have you taken a look at our document gallery? We have a wide range of subjects and types of documents, so let’s take a look at some documents!

I’m going to start by talking about the documents in the gallery which are content learning focused, then move into practice problems and a special document for studying.

First, let’s look at some calculus content learning documents! The calculus collection is our largest, reaching over 250 documents and still counting. The two documents I’ve picked from this category are our documents on the Fundamental Theorem of Calculus and a Visualization of Partial Derivatives. See a screenshot of the visualisations for each document below!

Are there other subjects you’d like to look at? Well, take a look at our list below!

Algebra: Double Vertical Asymptote Slider Graph

Graph Theory: Dijkstra’s Algorithm for Shortest Paths

Economics: Increase in Demand in a Market

Chemistry: Combined Gas Law Examples

Biology: Dihybrid Cross Punnett Squares

Physics: Displacement, Velocity, and Acceleration

We have many other subjects for documents, of course, but they wouldn’t fit in this post! Take a look at our entire document gallery for the others.

Another class of documents we have are the practice problems. Perfect for studying, we have practice problems ranging from practicing the four color theorem, to practicing mean, median, and mode, to even practicing dihybrid cross genotypes!
