Autograph softwareA Pair of Applets
I've updated one applet, Trigonometric Equations in Degrees, and added another version of the same applet, Trigonometric Equations in Radians
Accuracy is not guaranteed. The equations involving sin and cosine give reasonable accuracy, but the nature of the tangent function causes some rounding errors. They should make a useful pair for anyone studying the topic.
You can also try GED test which has study prep materials for the GED battery of tests.
New Sitemap
I have written a new sitemap to help with navigation around the site. There is also a link to it on the left and at the top of almost every page.
Another New Applet
There is another new applet - Inverses of 3×3 matrices - a calculator using determinants and cofactors.
A recent applet - Coordinate Geometry 1 on lengths and mid-points of line segments.
Take a look at my blog entry for this applet.
New Blog
I've launched a new Waldomaths blog. In future all new announcements will be on the blog. You're welcome to leave your comments and suggestions there, but note that they will be moderated. I'm relatively new to blogging so please let me know if I'm doing something wrong!
Other plans
- A number of applets for Algebra, Mechanics and Decision Mathematics
- More videos
- Hundreds of other small improvements
