How to Find the Inverse of a Function (With Examples) Math: How to Find the Tangent Line of a Function in a Point How to Find the Mean of a Probability Distribution How to Find the Slope of a Line Using the Derivative
Slope of a Polar Curve: To find the slope of the tangent line of a function, we normally just take the derivative to find {eq}\frac{dy}{dx} {/eq}. When polar equations are used, we can compute the derivative through the following formula: ...
Answer to: The tangent line to the graph of a function h at the point x=-5 is y=-(2x+14). Find the tangent line to the graph of y=xh(x) at x=-5. By...
题的意思是：求f(x)=8/√(x^2+3x)在点(1,4)处的切线方程 重点是求函数在x=1处的f'(x)直接求导很麻烦，可采用对数求导法，lnf(x)=ln8-(ln(x^2+3x))/2 两边同时对x求导，f'(x)/f(x)=-(2x+3)/2(x^2+3x)把x=1,f(x)=4带入，得 f'(x)=-5/2 可以求出切线方程为y...
Set the derivative equal to ( 0) then solve the equation( -e^(-x)x+e^(-x)=0). ( x=1) Solve the original function( f(x)=xe^(-x)) at ( x=1). ( 1/e) The horizontaltangentlines on function( f(x)=xe^(-x)) are ( y=1/e). ( y=1/e)反馈...
解析 Replace the variable( x) with ( 0) in the expression. ( f(0)=(sin)(0)(cos)(0)) Simplify ( (sin)(0)(cos)(0)). ( 0) Since the computed y-value is not the same as the y-value given, the point given is invalid. Invalid Point...
