Korea is the not only country in the world that is divided. The Korean peninsula consists of North Korea (officially the Democratic Peoples Republic of Korea) and South Korea (officially the Republic of Korea). Vietnam was divided til 1975. The Island of Cyprus is also divided due to the Cyprus Dispute between the Greek Cypriot-controlled Republic of Cyprus and the Turkish Cypriot-controlled Turkish Republic of Northern Cyprus. Only Turkey recognizes/acknowledges the Republic of Northern Cyprus. Furthermore, the nation of India was partitioned along religion into two states, India and Pakistan.
What does SEC mean in trig?
-
Secant (sec) - Trigonometry function
In a right triangle, the secant of an angle is the length of the hypotenuse divided by the length of the adjacent side. In a formula, it is abbreviated to just 'sec'.

The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x . The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .
Subsequently, question is, how do you find the SEC? The secant of an angle in a right triangle is the value found by dividing length of the hypotenuse by the length of the side adjacent the given angle. The secant ratio is the reciprocal of the cosine ratio.
In this way, is SEC a sin or cos?
Secant, cosecant and cotangent, almost always written as sec, cosec and cot are trigonometric functions like sin, cos and tan. Note, sec x is not the same as cos-1x (sometimes written as arccos x). Remember, you cannot divide by zero and so these definitions are only valid when the denominators are not zero.
Is SEC the opposite of Cos?
The cosecant is the reciprocal of the sine. The secant is the reciprocal of the cosine. The cotangent is the reciprocal of the tangent.
