tangent of 90°
Hi, I just reinstalled Geogebra Classic 5 to fix the Problem I got but unfortunately it didn't work.
If you try to teach students that the Tangent of 90 Degrees or Pi/2 rad is "infinity" it doesn't really work.
In the file I'm attaching you'll see what my Problem is if you put the slider to 90 so Beta is 90°.
C is the intersection of the Tangent (g) used to generate the tangent (tanb) of Beta.
Sorry if I messed something up with spelling, I usually do maths in German so I don't know all the English Terms.
