sec(347)

<-- Enter angle or number for inverse functions. Enter PI for π


Calculate sec(347)°
Since our angle is greater than 270 and less than or equal to 360 degrees, it is located in Quadrant IV
In the fourth quadrant, the values for cos are positive only.

347 is an obtuse angle since it is greater than 90°

Sec(θ) =1
Cos(θ)

sec(347) =1
Cos(347)

sec(347) =1
Cos(0.5)

sec(347) = 1
Since 347° is less than 90, we can express this in terms of a cofunction
(θ) = csc(90 - θ) = csc(90 - 347) = csc(-257)
