Solve for the interval 0 < x < pi/2
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
yes my calculator is in radians.
