FAQ
Frequently Asked Questions
No, it is very rare and primarily used in technical (mathematical) contexts or as informal slang from Spanish.
In English, it is typically pronounced /sɛtʃ/ (like 'setch') when referring to the mathematical function.
Only in informal slang, borrowing from Spanish, where it means 'look' or 'see'. This is non-standard and not widely recognized.
'sec' is the trigonometric secant (1/cos), while 'sech' is the hyperbolic secant (1/cosh). They are different functions used in different branches of mathematics.
A mathematical function, the hyperbolic secant, defined as sech(x) = 1 / cosh(x) = 2 / (e^x + e^-x).
Sech is usually technical (mathematics, engineering) or informal (slang from spanish influence) in register.
