Description
~~~~~~~~~~~

The Trigonometric Function block performs numerous common
trigonometric functions. You can select a function among those quoted
in this table :


**Function** **Definition** **Output** sin Sine of the input (radians)
y = sin(u) cos Cosine of the input (radians) y = cos(u) tan Tangent of
the input (radians) y = tan(u) asin Inverse sine (radians) of the
input y = asin(u) acos Inverse cosine (radians) of the input y =
acos(u) atan Inverse tangent (radians) of the input y = atan(u) atan2
Four quadrant inverse tangent (radians) of the input y = atan2(u) sinh
Hyperbolic sine of the input y = sinh(u) cosh Hyperbolic cosine of the
input y = cosh(u) tanh Hyperbolic tangent of the input y = tanh(u)
The block output is the result of the applied function on the scalar
input or on the vector's elements of input.
