為什麼這篇magnitude數學意思鄉民發文收入到精華區：因為在magnitude數學意思這個討論話題中，有許多相關的文章在討論，這篇最有參考價值！作者eri820503 (money)看板Math標題[微積] 大一微積分 不過好像在考物理.能幫一...
An object with mass m is dragged along a horizontal plane by
a force acting along a rope attached to the object. If the rope
makes an angle θ with the plane, then the magnitude of the force
is
μmg
F=-------------
μsinθ+cosθ
where μ is a constant called the coefficient of friction.
(a) Find the rate of change of F with respect to θ
(b) When is this rate of change equal to 0
順便問一下 respect在數學上的意思
有人能幫忙嗎?!
謝謝
