Question

lingo中怎么表示反三角函数例如要表示y=arc cos(x)

Answer 1

@ACOS( X)

Returns the inverse cosine,or arccosine,of X,where X is an angle in radians.

@ACOSH( X)

Returns the inverse hyperbolic cosine of X,where X is an angle in radians.

@ASIN( X)

Returns the inverse sine,or arcsine,of X,where X is an angle in radians.

@ASINH( X)

Returns the inverse hyperbolic sine of X,where X is an angle in radians.

@ATAN( X)

Returns the inverse tangent,or arctangent,of X,where X is an angle in radians.

@ATAN2( Y,X)

Returns the inverse tangent of Y/X.

@ATANH( X)

Returns the inverse hyperbolic tangent of X,where X is an angle in radians.
