Differentiate
I did this:
u= and y=6sinu

=6cosu =

The answer is meant to be 3cossqrtx / sqrtx
How do you get that? If you times it together it doesnt come to that ? :|

P.S Merry Christmas everyone (and for those not celebrating) Merry Saturday!

That's the same as

Because multiplication is multiplication - it doesn't matter if you do 6x8 or 8x6. So it doesn't matter if you do (1/2)*(x^-1/2)*(6) or (x^-1/2)*(6)*(1/2) or (1/2)*(6)*(x^-1/2).

You should probably be able to figure out what is as a fraction now if you already didn't know
