Best ResponseYou've already chosen the best response.3do you mean \(\Large W = \arcsin (x/a)\) and you want to find its derivative with respect ot x ?

Best ResponseYou've already chosen the best response.0\[w=\frac{ Arcsin \alpha }{ \alpha}\] its written that way in my book and it asks for its derivative..

Best ResponseYou've already chosen the best response.0.. is it the the denominator be squared then the multiply the denominator with the derivative of the numerator minus the numerator time the derivative of the denominator...

Best ResponseYou've already chosen the best response.3\(\Large \left[\frac{f(x)}{g(x)}\right]'=\frac{g(x)f'(x)f(x)g'(x)}{[g(x)]^2}. \)

Best ResponseYou've already chosen the best response.0i already knew that one.. but my book says that the answer to the problem is zero... i dont get it

Best ResponseYou've already chosen the best response.3in our case, f(x) = arcsin x g(x) =x what is f'(x) and g'(x) ?

Best ResponseYou've already chosen the best response.3`derivative of a constant is 0.` so maybe your text book is not asking for the derivative with respect to \(\alpha \)

Best ResponseYou've already chosen the best response.3for any other variable, W will be a constant, and the derivative will be = 0

Best ResponseYou've already chosen the best response.0why is it that the W is a constant?

Best ResponseYou've already chosen the best response.3because W is the function of \(\alpha\) only if \(\alpha\) is NOT a variable, then W is also not a variable
