Homework Statement
In D3, simplify f = u R u R
Homework Equations
The Attempt at a Solution
u(Ru)R=(uR)uR
u(uR^2)R=(uR)u2
uR=R
I am doing this for independent study, and the website I am using says the solution is 1=R
I just got started on dihedral groups and have no idea what in the heck to do. How do you tell which is a rotation or reflection before the solution arises and/or arrive with the above answer of R=1
Thanks
