Solve for the interval 0 < x < pi/2

[tex]\sqrt{5}Cos(2x+0.464)[/tex]

2. Relevant equations

3. The attempt at a solution

Am i right in saying as cos oscillate between -1 and 1:

The maximum is sqrt(5) and occurs when (2x-0.464) = 1

Now i got 0.464/2 and (2pi - 0.463)/2

and the back of the book says 0.32 and 2.36

How do you solve equations like above :S

Thanks

yes my calculator is in radians.
