The approximate value of the expression sec 4π / 13 is 1.76
Radian is a unit of measurement of angles equal to about 57.3° . equivalent to angle subtended at the center of a circle by a arc equal to length of radius
To Change Radian into degree, we multiple the angle with 180/π
The given Expression is
sec 4π / 13
Changing radian into Degree ,
=> 4π / 13 × 180 / π
=> 720 / 13
=> 55.38
Therefore , sec 55.38° is 1.7603
rounding off to two decimal places is 1.76
