In physics it is important to use mathematical approximations. Demonstrate that for small angles (<20 deg) tan x ~sin x~ x=pi*x'/180 deg where x is in radians and x' is in degrees. What is the largest angle for which tan x may be approximated by sin x if the error is to be less than 10.0%

Please show work.

why do dolphins...?
I heard on a program that dolphins have a thin layer of water surrounding their bodies that reduces and almost completely gets rid of any drag, and I was wondering what caused them to always have that layer? What makes it stay with them?


I originally posted this under zoology, but now I realize it probably has more to do with physics.

Hello-
I was wondering if a vector can have a nonzero magnitude if a component is zero? If it can't then why? If it can could you give me an example?
Thanks!!!

the object was dropped some distance above you.
answer in form of a formula. L , g(gravity), t (the time you saw an object falling for a given length), and the height at which it was dropped (assuming that it stopped dropping after you saw it disappear)

After 9/11 US attacked afghanistan, then attacked iraq, really stupid.......9/11 carried out by Bin Laden has his base in pakistan, why the hell does he not attack pakistan. No wonder we saw more attacks in spain and uk.

Pakistan and saudi are the real threats, Bush wake up shoot the real terrorists.
