Hello all,

Am struggling to get to grips with some problems set to me.
Any help would be great!!

1) Differentiate with respect to x:

a) y = 5 / 3sqrt x

b) y = 1/2 sin x + 1/6cos 3x

c) y = x^2 + ln2x+e^2x

2) Differentiate the following functions:

a) y = (3x-2x^2)(5 +4x)
b) y = 5xsinx
c) y = xe^x/2

Thanks in advance

Giles
