TrigFun

Trigonometric function

Block Screenshot

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 2-quadrant and 4-quadrant inverse tangent (radians) of the input y = atan(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.
