function not working
Not a Problem
The function f(x) works
f(x) = x + 2
a = f(6) = 8
and this equation here works
{{cos(pi/2),0,sin(pi/2)},{0,1,0},{sin(pi/2),0,cos(pi/2)}} * Vector(3,4,2) = Vector(2,4,3)
But this function doesn't work
R(x) = {{cos(x),0,sin(x)},{0,1,0},{sin(x),0,cos(x)}}
v = R(pi/2) * Vector(3,4,2) = Vector(?,?,?)
can someone tell me why it wont work or how to fix it?https://www.geogebra.org/cl...

I have a workaround in CAS

packed in take(matrix,firstrow,lastrow)
and closed with keep input
no other way...
