Question

Pz tell me the relation between cosec and tan ??

Answer 1

Sec, Cosec and Cot

Secant, cosecant and cotangent, almost always written as sec, cosec and cot are trigonometric functions like sin, cos and tan.
sec x  =    1 
              cos x
cosec x =    1      
               sin x
cot x =      1       =   cos x
              tan x         sin x
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.



thats all........
