Find the equation of line tangent to the graph of f(x)=e+ln x at x=1? 答案 e是常数,f'(x)=1/x,所以切线在x=1点的斜率是1,在x=1点的函数值是e.So the equation of the tangent line of graph at x=1 is f(x)=x+e-1相关推荐 1Find the equation of line tangent to the grap...
When calculating a line tangent to a graph, you need to know a point and the instantaneous rate of change at that point. In this example, the point (3,1) is provided. The derivative of the function is used to find slope, but y is not explicitly defined in terms of x. It is ...
