In other words, for every point on the graph of f (x)=e^x, the slope of the tangent is equal to the y-value of tangent point. So if y= 2, slope will be 2. if y= 2.12345, slope will be 2.12345 2 comments ( 25 votes) Upvote
WebAnswer: First, you need to define z in terms of its real and imaginary parts. In electrical things, there is only a single independent variable. It would be t. In general though, you could have z = f(x) + j*g(y), where j is the square root of -1. Then you would have to take partial derivatives wi...
