Ok, then what about in a question such as ysin(x)+e^{x^{2}y}=\sqrt{x+y} This is what is confusing me. In this case will both x and y be variables?

The question asks to differentiate (2nb^{rx}+n)^{k} However, the problem is that it doesn't specify with respect to which variable should the derivative be taken. When the question asks to differentiate, does it mean that we should take the derivative for each and every variable, one by one?

Have sent u a PM Sammy.

As I'm a university freshman, so basically I'm unfortunately unfamiliar with modular arithmetic or the mod() function. You can think of me as a rookie in Calculus.. so on the basis of that I should be solving this problem. What are the options I have as a fresher? Thanks a lot to everyone for...

Thanks again for your kind replies. I'll treat them separately and then check my results. Will also follow the binomial theorem as a alternative way to check my results. Thanks tim. But is there a possibility to give one general formula? I've been asked to give one formula so... :( I'll try...

@ tiny-tim, are u sure the general formula can be obtained by using the binomial theorem? I basically have to get the general formula on the basis of the five derivatives I have calculated. I have to use them as a basis for my general formula.

Thanks a lot SammyS and tiny-tim for your kind reply. Basically, I need to find a general formula for the derivative such that (f)''=-2 sin(x) - x cos(x). The pattern which I observed is that when n is an even number like 2 or 4, sin(x) is the first element of the derivative and the value of...

Finding the General Formula for derivative (nth formula) Given function = (x*cos(x)) or xcos(x). Need to find the general formula for the derivative when n=n and test it for n=2 or 3. I have taken the first five derivatives and observed a pattern, however, I'm not exactly getting the correct...
