I am the OP. Please refer to my post #16 above. I will work out the details if you need me to.

The symbols ##\lambda## and ##\mu## are fractions. Thus, what I mean is, ##\vec {AP} = \mu \vec{AE}##, for instance, or that ##\vec {BP}...

Attempt : I attempt the problem making A as the origin, written with (O) in bold above A, in the diagram. Thus, ##\vec e =...

I have already done it that way, integrate with respect to ##x## and faced no problems. (Please see at the beginning of my post #1...

I agree with you, but there's a basic discrepancy that bothers me here. If you want to find out the arc length ##s## integrating with...

Statement of the problem : Calculate the arc length ##s## of the quadrant in the figure shown alongside. Attempt : (I have been able to...

Of course not. Indeed I could have chosen a point on the parallelogram like A as you suggested. I would do it presently, but first...

I choose an arbitrary origin O and draw the relavant vectors ##\vec a, \vec b, \vec c## by hand to the three vertices of the...

Look at the coefficients of the vector ##\vec a## in his two equations. He (@BvU) is right and it was me who was wrong. It gives me hope...

Changes : The three equations involving the coefficients ##\lambda,\mu##above, assuming linear independence of vectors ##\vec a, \vec...

Statement of the problem : I copy and paste the statement of the problem as it appears in the text to the right. Additionally, I prove a...

Yes I was aware of this, but didn't succed when I tried to do the same problem your way. Let me show you the little I could do. Problem...
