Oh god! Of course. I must not be feeling well. Thanks.

My TI-89 calculator rearranged $$ 2^{2m+1}-1$$ to $$ 2\times 4^m - 1 $$ I can't for life of me work out how it did it. Is anybody able to put me out of my misery? Thank you in advance! Ben

Excellent, thanks for the help, I've figured it out now. I wasn't thinking about Kirchoff's Current law.

It'll be easier with diagrams, I've attached an image which shows the path I've chosen.

Hey Steve and Dave, Yea it's pretty hot in Sydney right now! Think Victoria and SA are getting slammed by the bush fires. Dave it must be hot out your way today! I'm Northern Beaches myself. I'm actually Pomme, but have an Australian passport now.

Hi gneill, Thanks for the reply. I've attached a circuit diagram I've drawn with arrows showing the path of the current. Is this the correct path of the current? If so, then I would say there is a potential of 12v between the ground and node X.

Homework Statement The question requires viewing the circuit diagram to start. An image is attached, it can also be viewed here (http://imgur.com/6Q0DCQ9). The questions are: a) Calculate the equivalent resistance ##R_T## of the 4 ##\parallel## 8 ohm combination. b) Redraw the circuit with...

G'day! So far from what I have learnt, Calculus has been most interesting to me.

Hi everyone. I am in my early 30's and and am about to undertake a Bsc in Mathematics. I am currently taking a foundation course in Physics. Obviously Mathematics and Physics is a passion of mine, particularly Astronomy, Cosmology and Astrophysics. I'm currently having some trouble with...
