These functions are simply the reciprocals of sine, cosine, and tangent. Cotangent is the reciprocal of tangent. Its formula is: It's also possible you might have to deal with cosecant, secant, and cotangent in questions that cover trigonometric identities (we'll cover the important identities later in this chapter).
Just so, what is the COT in math?
cotangent(q) = adj/opp. The functions are usually abbreviated: sine (sin), cosine (cos), tangent (tan) cosecant (csc), secant (sec), and cotangent (cot). It is often simpler to memorize the the trig functions in terms of only sine and cosine: sine(q) = opp/hyp.
Is COT the same as 1 tan?
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.
