Step by step video & image solution for यदि ylogx=x-y हो, तो सिद्ध कीजिए कि- dy/dx=(logx)/((1+logx)^(2)) by Maths experts to help you in doubts & scoring excellent marks in Class 12 exams. ...
If u(x,y)=y log x+x log y, then u_(x)u_(y)-u_(x)log x-u_(y)log y+log x log y= A body is executing a simple harmonic motion such that its potential energy is U_(1) at U_(2)at y When the displacement is x+y the potential energy will be Trajectories are shown in...
不成立。右边式子括号里面应该是x除于y
x/y=x-y x*（1/y -1）=-y x=y^2/（y-1）
Answer to: if y to the power x = x to the power y, prove that dy/dx=y/x(y-xlogy/x-ylogx) By signing up, you'll get thousands of step-by-step...
易知x>y>0log(x/y)=log(x-y)x/y=x-yx=yx-y²(y-1)x=y²x=y²/(y-1) (y>1) 解析看不懂?免费查看同类题视频解析查看解答 相似问题 log(x/y)=logx-logy log(X+Y)=logX+logY,则X+Y取值范围 logx+logy=2lg(x-2y) 求log√2 (x/y)值 ...
"We have "x^(y)=e^(x-y) "or "e^(ylog x)=e^(x-y)" "[becausex^(y)=e^(log x^(y))=e^(y log x)] "or "ylog x = x-y "or y=(x)/(1+log x) On differentiating both the sides w.r.t. x, we get (dy)/(dx)=((1+log x)xx1-x(0+(1)/(x)))/((1+ log...
就是对数的函数关系。
叫对数函数。y等于logx那么x等于什么 y=logx，即x=10的y次方 此问题是求函数y=logx的反函数 在数学中，对数是求幂的逆运算，y=logx中，log是log10的简写写法，底数是10，即指数函数的底数是10，函数值y是指数，x是真数，即x就是10的y次幂 因此得到y=logx的反函数x=10的y次方，其中y∈R ...
