B Point, f Line
Want to calculate Reflect(B, f) in CAS with function vector eo, vector no
- s(eo,no):=eo - (2/sqrt(no^2)*Dot(eo,no) )* no/sqrt(no^2)
- >s(eo, no):=((2 * no) * ((((x * eo) * x) * no) + (((y * eo) * y) * no) + (((z * eo) * z) * no)) / no^(2)) + eo
what about x,y,z in Output?
s(eo, no):=(((-2) * no) * ((((x * eo) * x) * no) + (((y * eo) * y) * no) + (((z * eo) * z) * no)) / no^(2)) + eo
It is possible to handle vectors/lists in functions?

The same problem 
Try entering this in "Keep Input" mode:
Ahhh,
very usefull, Thank you very much!
this solves https://help.geogebra.org/t...# , too!
Same problem (dispatcher prop?)...
I want add my Sig

Mist,
the game is not over - new problem
Function does not compute correct...

Line 7 Functiondef
Line 9 fitting function results to matrix
Line 10 result expected

Strange, it seems to be swapping the arguments of s() over, try
We'll check!
hm,
swap arguments
s(no,vo):=vo - 2 Dot(vo, no)/Dot(no, no)*no
Append(Append({Flatten(s(n,e1))},Flatten(s(n,e2))),Flatten(s(n,e3)))
cool - does correct calculation
but should run otherway too?
hawe
