Given f (x) = 2Sin (2x + π / 3) + 1, find the minimum positive period and maximum value of F (x) and the value of X at this time

Given f (x) = 2Sin (2x + π / 3) + 1, find the minimum positive period and maximum value of F (x) and the value of X at this time

The maximum positive period is obviously π. The maximum value is simpler. The range of trigonometric function is - 1 to + 1, so the maximum value is 2 + 1 = 3
The second is the value at this time, that is, when the trigonometric function is equal to 1, (2x + π / 3) = 90 degrees, that is 15 degrees. I don't know if I read it wrong. These basic trigonometric function problems are very simple. If you look at the definition and figure, you can do it yourself for no more than ten seconds
