cos(x-y)=xy for x>0.5

a.find the smallest two positive values x>0.5 for which y(x)=0

b.find the global minimum of y(x) for x>0.5

c.call the numbers you found inpart(b) x1 and x2 find

integral of y(x)dx from x1 to x2

## Homework Equations

## The Attempt at a Solution

a.One of the two positive values is pi/2 and another one is 3*pi/2

b.I could not figure this out.

c.- 2*cos(y) – pi^2*y
