Hi SammyS
I wrote that first sentence wrong, I meant 'I am told this is right, but I think its wrong'. See? If I can't put a sentence together what hope do I have in algebra?! This is an example I got given and need to show the processes. I've solved all the others given to me except this...
Seriously, my algebra is terrible. So I take out a factor that is common to both sides? I take it you mean both sides of the equals sign. That would be the 'ab' then. But when you say 'take out' I'm not sure what you mean. Like this?
ab*1/(2c(d+e))+ab*1/(2c(d-e))=ab*d/(c(d^2-e^2))
Homework Statement
I am told this is wrong, but I am convinced it is right. I just need to show how but don't have a clue.
Homework Equations
(ab)/(2c(d+e))+(ab)/(2c(d-e))=(abd)/(c(d^2-e^2))
The Attempt at a Solution
I do not have a clue where to start. I am clueless as...
Ah, ok, so my problem here appears to lie with my grappling with the units. My answer comes out as 3.9884521*10^14 m^3 s^-2 (metres!) so, if I converted that into km^3 s^-2 I would have to divide that by 1000^3, thereby ending up with the accepted value! This would explain my confusion...
Homework Statement
Don't laugh! I am scratching my head. Somewhere I am doing something very stupid, but I just don't know where. My problem is that my result of G*M of Earth is different than the accepted result of G*M.
Accepted value of G*M: μ = 398600 km^3 s^-2
