Okay, after what you wrote, I think I'll buy the "Introduction...", it's safer ;) And also start with learning maths - I guess it's better to check if I'm able to understand such things (like partial differential equations *.*) before buying a book that uses them everywhere ;p
Thanks a lot ! :)
Thanks rcgldr and HossamCFD :)
Hossam, could I ask you which of the books you recommend the most ? I'd be great to read them all, but they're expensive :( And what do you mean by "higher level" ? thx
Thank you K^2 ! But If I knew where to find those things I wouldn't have asked :( Well, I found one book that is (wow, at least one..) available in my country and that seems fine to me, and this is an excerpt from it: http://home.comcast.net/~clipper-108/lift.htm
Do you think it is a good...
Hi, I got really interested in aircrafts (aerodynes) recently and I would love to know more about it. But I have no idea where to start. Better to start with some Physics background first (I used to be interested in Physics, but I dropped it like 2 years ago; I'm returning to it now but still...
I'm so stupid ! the last part (dh/dt) should be:
\frac{d}{dt}(\frac{h}{1000})=\frac{1}{1000}\frac{dh}{dt}
Right ?
And thank you for help :) I'd been already really upset; I thought the whole solution was wrong and didn't know why.
And of course "100" was only when t=10s. I just hadn't...
Homework Statement
A rocket has launched straight up, and its altitude is h = 10t2
feet after t seconds. You are on the ground 1000 feet from the launch site. The line
of sight from you to the rocket makes an angle θ with the horizontal. By how many
Radians per second is θ changing ten seconds...
