In summary, the conversation discusses the problem of finding the derivative of y=e^nx and the correct answer is n^2e^nx. However, the person asking the question mistakenly assumed it was a second derivative. The other person in the conversation corrects them and reminds them not to assume and to follow the given instructions.

The problem says that if y=e^nx, then d^ny/dx^n=?

I got that the result is n^2e^nx, but it is not among the offered choices. Can someone tell what did I mess up? Thanks.

You're not differentiating twice, like you did ([tex]n^{2}e^{nx}[/tex]), but "n" number of times.

Oh I see. I guess I shouldn't have assumed that it is a second derivative. Thanks for the help.:smile:

Yes, in general it is a mistake to assume something when you are told differently!
 

FAQ: Solving y=e^nx: What's the Result of d^ny/dx^n?

What is the equation for y=e^nx?

The equation for y=e^nx is a basic exponential function where e is the base of the natural logarithm and n is the exponent. It can also be written as y=ex^n, where x is the independent variable.

What does d^ny/dx^n represent in the context of solving y=e^nx?

d^ny/dx^n represents the nth derivative of y with respect to x. In other words, it is a measure of the rate of change of the exponential function y=e^nx at a specific point on the curve.

How do you solve for d^ny/dx^n in the equation y=e^nx?

To solve for d^ny/dx^n, you will need to take the nth derivative of the exponential function y=e^nx. This can be done using the chain rule, where you multiply the original function by the derivative of the exponent, n, and then take the derivative of the exponent itself. The resulting equation will be d^ny/dx^n=ne^nx.

What is the value of d^ny/dx^n when n=0 in the equation y=e^nx?

When n=0, the equation y=e^nx simplifies to y=e^0, which equals 1. Therefore, the value of d^ny/dx^n when n=0 is 0, as the derivative of a constant is 0.

How does the value of n affect the graph of the exponential function y=e^nx?

The value of n affects the slope of the graph of y=e^nx. A larger value of n results in a steeper slope and a faster rate of growth, while a smaller value of n results in a flatter slope and a slower rate of growth. Additionally, a negative value of n will cause the graph to reflect over the x-axis, while a positive value of n will not.
