Find (d^2y)/(dx^2) in terms of x and y: xsiny=3 How to solve this?
The question is asking that you find the second derivative with respect to x. Do you know how to take a derivative?
For the first derivative, you will be using the product rule. Since you have two functions being multiplied \[f \frac{ d }{ dx }g+g \frac{ d }{ dx } f\]
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.
thank you, i'll try ^^
