what is the difference between the term csec,sec,and arcsin arccos math?
- ricksonLv 51 decade agoFavorite Answer
Cosec and sec are the reciprocals of SIN and COS.
Arc cos(X) is the angle whose cosine is X
Arc sin(X) is the angle whose sin is X

the co-secant is the reciprocal of the sine function while arcsin is the inverse of the sine function.
Secant is the reciprocal of the cosine function while arccos is the inverse of the cosine function.
They are terms commonly misunderstood until you remember the difference between inverses and reciprocals.

cosec and sec are trig functions, similar to sine and cosine, you put in an angle and calculate the function.
arcsin and arccos are inverse functions, in other words you know the sine or cosine and you calculate the angles. It's nearly all calculator stuff.

sec = 1/cos
cosec = 1/sin
arcsin is the inverse of sin
arccos is the inverse of cos.
note that the inverse of sin is not 1/sin.
note that the inverse of cos is not 1/cos
