## anonymous 3 years ago Find (d^2y)/(dx^2) in terms of x and y: xsiny=3 How to solve this?

1. abb0t

The question is asking that you find the second derivative with respect to x. Do you know how to take a derivative?

2. abb0t

For the first derivative, you will be using the product rule. Since you have two functions being multiplied $f \frac{ d }{ dx }g+g \frac{ d }{ dx } f$

3. abb0t

Also note, that the derivative of a constant is just zero. So the 3 becomes zero. For the second derivative, you will be doing product rule again.
