Centralised Licensing For Windows Networks
If you have a network administrator that complains every year about having to re-license computers on an FX MathPack subscription, or if you spend months pleading to get your subscription updated, forward this email to your computer services department!
We have implemented a new centralised licensing option that allows network administrators to store licence files in one central location. This means that extending a subscription can be as simple as editing one file on a central server. It has the potential to make network administrator’s lives much easier AND might mean less time on the phone for you as you try to get them to install the licence.
The new system is discussed on our support pages.
Licensing Efofex Products on Windows Networks
Centralised Licensing will be implemented for FX SciencePack once FX Chem 3 and FX ChemStruct 2 are released.
FX Chem 3
We have uploaded beta versions of FX Chem 3 for both Windows and Mac. A long time user of FX Chem 2 (and FX Chem 2 has been around a long time) recently said “I don’t know what else you could add!” Well, we have found a few things worth doing but you can rest assured that we have not changed it too much.
What’s New? Obviously, Mac compatibility was a major focus during development but we have also added the ability to change formatting for bits of an equation. This lets you highlight one reagent in red for instance.
We have also improved integration with Word for Windows making the process more seamless.
Finally, we have added a number of new output formats that let you produce equations that embed natively into Word as well as LibreOffice, Latex and even Moodle.
FX Equation
Thanks yet again to our dedicated band of beta testers, we are releasing FX Equation 5 for both Windows and Mac.
New Features
FX Equation 5 adds some nifty new features and is much more than just a Mac release.
FX MathPack
The new FX Equation has been added to the current FX MathPack download and subscribers can start using FX Equation 5 straight away.
Question:
I was hoping you could tell me how to begin a histogram at 0. When I do a histogram the first bar starts before 0. I can change the width but can’t seem to change where the histogram begins.
Answer:
The histogram tool will group your raw data as best it can but, if you do not like what it does, the best thing to do is to create your own groups. That way you can produce anything you like.
FX Stat also has the capability to group your raw data into groups that you define but that is a different process.
Question:
Why are these perpendicular angle marks being drawn as squares? I just want two lines.
Answer:
Although it is not obvious from your diagram, this is because you are drawing shaded angle marks and the shading has been set to white. When angle marks are shaded, they draw the complete square.
Here I have marked an angle as perpendicular and shaded it. In your case the shading is white but I have made it green so that you can see it. To get a normal perpendicular mark, select the angle mark (as shown above) and change the shading to none.
When there is no shading attached to the angle mark, FX draw will only draw the two lines rather than the square.
Question:
The angle marking tool is not allowing me to mark the angle I want. How can I fix this?
Answer:
I think your question is relating to this situation – where you are trying to mark angle ABC but the angle marking tool is always finding ABD or DBC.
Question:
How do I shade the area 
what formula should I put in? I have (y=x4+1, y=1, y=3)
Question:
How do I draw a semicircle?
Answer:
There are a few options but probably the easiest way is to use the arc defined by centre and two end points tool.
Question:
Can you show me how to shade the area between the curves step by step?

Answer:
FX Graph/Draw can only find integrals between functions and the red curve is a relation. To get what you are after, we need to add a function that FX Graph can use. In this case, the function is y=sr x. Continue reading
