Question

What is the trick with hw4 #2. I have gOA and qO1 and I want qA1. Do I transpose the rotation matrix of gOA?

Answer 1

Ok if we want \[q ^{A}_{1}\] and we have \[q ^{O}_{1}\] then we can calculate \[q ^{A}_{1}\] as \[q_{1}^{A} = g _{O}^{A}*q_{1}^{O}\]Thus the only thing we need is \[g ^{A}_{O}\] which is the inverse transformation of \[g ^{O}_{A}\] Dr. Vela talked about how to do an inverse transformation in class Thursday. Do you have the formula?

Answer 2

I do. Thanks.
