Csc, sec functions
Hello,
I have not yet seen a calculator that has a dedicated key for the cosecant , secant, nor cotangente functions, because they are directly connected with the sine, the cosine, and the tangente.
Cosecant (x) = 1/sin(x)
Secant (x) = 1/cos(x)
Cotangente(x) = 1/tan(x)
Do not confuse these functions with the inverse trigonometric functions, usually represented as
arccosine = arccos; on calculators cos^-1,
arcsine = arcsin ; on calculators sin^-1
arctangent= arctan ; on aclculators tan^-1
Hope it helps.
