At what points in the interval `[0,2pi]`, does the function `sin 2x` attain its maximum value?

Explanation

Maximun value of function `sin(2x)` is `1` and that happens when


`x=((2n+1)pi)/2` {Where n is `(0,1,2,..........)`}


so number of places where `sin(2x)` will attain maxima in the given domain will be at


`x=pi/2,(3pi)/2`
