Hello, could sumone do this for me:
Derivative of (x)^1/2 * sin^-1(of)(1-x)^1/2

Thanks

Would the question read:

x1/2*sin-1(1-x)1/2

=( (1/2) (x)^(-1/2) )* asin((1-x)^(1/2)) - (x^(1/2))*(((1/2)*(1-x)^(-1/2)) * (1)/((1 - (1-x))^1/2))

I did that quickly

you can check with graphmatica

EDIT: mabye not, graphmatica screws up complex differentials

>> syms x

>> f = ((x)^(1/2)) * (asin((1-x)^(1/2)))

f =

x^(1/2)*asin((1-x)^(1/2))

>> diff(f,x)

ans =

1/2/x^(1/2)*asin((1-x)^(1/2))-1/2/(1-x)^(1/2)

>>

EDIT: btw, MATLAB = death for 2/3U students :p, so don't use it
