What is SECH in math?

Sech is the hyperbolic secant function, which is the hyperbolic analogue of the Sec circular function used throughout trigonometry. It is defined as the reciprocal of the hyperbolic cosine function as . Sech[α] then represents the reciprocal of the horizontal coordinate of the intersection point.

What is Csch in math?

Csch is the hyperbolic cosecant function, which is the hyperbolic analogue of the Csc circular function used throughout trigonometry. It is defined as the reciprocal of the hyperbolic sine function as . Csch may also be defined as , where is the base of the natural logarithm Log.

What is Sinhx?

Hyperbolic cotangent: coth(x) = cosh(x) sinh(x) = ex + e−x ex − e−x.

How do you write SECH in Matlab?

What weapon is a cosh?

A club (also known as a cudgel, baton, bludgeon, truncheon, cosh, nightstick, or impact weapon) is among the simplest of all weapons: a short staff or stick, usually made of wood, wielded as a weapon since prehistoric times.

How do you write Coshx in Matlab?

Y = cosh( X ) returns the hyperbolic cosine of the elements of X . The cosh function operates element-wise on arrays. The function accepts both real and complex inputs. All angles are in radians.

What does cosh mean?
