工程數學一階ode 通解表示
再思考一個問題就是寫一階ode時隱函數通解f(x,y)=c
想說如果左邊的x跟y變數項跑道右邊這樣也算隱函數通解嗎?
例如 x*exp(y)=x+2/y+c 或 x^2+y^2=sin(x)+c
我的右邊變數項不整理到左邊這樣會不會被扣分阿??
另外 通解裡面有分母會不會被扣分?
比如說一階線性ode 1/y=x^2+c/x 我是不是應該要同乘xy讓分母消失才算做完呢?<div></div> 不會~~
ie. f(x) = y = mx + c , this is not a implicit function
but if we rewrite the function , ie. z = f(x, y) = mx - y + c
we obtain that , the function z is defined by a relation between argument of x and value
of y
since , z is a implicit function
at last question , you must ask your math teacher {:45:}
