ANYONE???

Q 5i) dy/dx = 8 * (1/2)cos(1/2)x - (1/2)sec^2(1/2)x

dy/dx is zero at maximum point.

so

0 = 8 * (1/2)cos(1/2)x - (1/2)sec^2(1/2)x

(1/2)sec^2(1/2)x = 4cos(1/2)x

sec(x) = 1/cosx

so

sec^2(1/2)x = 1/cos^2(1/2)x

1/cos^2(1/2)x = 8 cos(1/2)x

1 = 8 cos^3(1/2)x

cos^3(1/2)x = 1/8

cos(1/2)x = 1/2

(1/2)x = pi/3

x = 2pi/3

When they ask for an Argand diagram, do we draw it on the given graph paper or on the answer booklet?

If anyone's awake, please answer...
