Find a positive angle less than one revolution around the unit circle that is co-terminal with the given angle: 52π/5

The required angle is

Step-by-step explanation

The  given angle is .

To find a positive angle which is coterminal with and is less than one revolution,

we subtract multiples of until we obtain an angle between .

Let the positive angle less than one revolution that is coterminal with    be , then

,

We simplify to get,

We collect LCM to obtain,

The correct answer is A

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
