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^{-}**x (sometimes written as arccos x). Remember, you cannot divide by zero and so these definitions are only valid when the denominators are not zero.**^{1}
