Trigonometric

sin function

Returns the sine of the argument.

sin(z)

Description

The `sin` function calculates the sine of an angle `z`, which may be in radians or degrees depending on the current settings. `z` may be any numeric expression that evaluates to a real number or a complex number. If `z` is a real number, the result will be in the range -1 to 1.

Remarks

For arguments with a large magnitude, the function will begin to lose precision.

cos function

Returns the cosine of the argument.

cos(z)

Description

The `cos` function calculates the cosine of an angle `z`, which may be in radians or degrees depending on the current settings. `z` may be any numeric expression that evaluates to a real number or a complex number. If `z` is a real number, the result will be in the range -1 to 1.

Remarks

For arguments with a large magnitude, the function will begin to lose precision.

tan function

Returns the tangent of the argument.

tan(z)

Description

The `tan` function calculates the tangent of an angle `z`, which may be in radians or degrees depending on the current settings. `z` may be any numeric expression that evaluates to a real number or a complex number.

Remarks

For arguments with a large magnitude, the function will begin to lose precision. `tan` is undefined at z = p*π/2, where `p` is an integer, but the function returns a very large number if `z` is near the undefined value.

asin function

Returns the inverse sine of the argument.

asin(z)

Description

The `asin` function calculates the inverse sine of `z`. The result may be in radians or degrees depending on the current settings. `z` may be any numeric expression that evaluates to a real number. This is the reverse of the `sin` function.

acos function

Returns the inverse cosine of the argument.

acos(z)

Description

The `acos` function calculates the inverse cosine of `z`. The result may be in radians or degrees depending on the current settings. `z` may be any numeric expression that evaluates to a real number. This is the reverse of the `cos` function.

 Wikipedia MathWorld

atan function

Returns the inverse tangent of the argument.

atan(z)

Description

The `atan` function calculates the inverse tangent of `z`. The result may be in radians or degrees depending on the current settings. `z` may be any numeric expression that evaluates to a real number. This is the reverse of the `tan` function.

 Wikipedia MathWorld

sec function

Returns the secant of the argument.

sec(z)

Description

The `sec` function calculates the secant of an angle `z`, which may be in radians or degrees depending on the current settings. sec(z) is the same as 1/cos(z). `z` may be any numeric expression that evaluates to a real number or a complex number.

Remarks

For arguments with a large magnitude, the function will begin to lose precision.

 Wikipedia MathWorld

csc function

Returns the cosecant of the argument.

csc(z)

Description

The `csc` function calculates the cosecant of an angle `z`, which may be in radians or degrees depending on the current settings. csc(z) is the same as 1/sin(z). `z` may be any numeric expression that evaluates to a real number or a complex number.

Remarks

For arguments with a large magnitude, the function will begin to lose precision.

 Wikipedia MathWorld

cot function

Returns the cotangent of the argument.

cot(z)

Description

The `cot` function calculates the cotangent of an angle `z`, which may be in radians or degrees depending on the current settings. cot(z) is the same as 1/tan(z). `z` may be any numeric expression that evaluates to a real number or a complex number.

Remarks

For arguments with a large magnitude, the function will begin to lose precision.

 Wikipedia MathWorld

asec function

Returns the inverse secant of the argument.

asec(z)

Description

The `asec` function calculates the inverse secant of `z`. The result may be in radians or degrees depending on the current settings. asec(z) is the same as acos(1/z). `z` may be any numeric expression that evaluates to a real number. This is the reverse of the `sec` function.

 Wikipedia MathWorld

acsc function

Returns the inverse cosecant of the argument.

acsc(z)

Description

The `acsc` function calculates the inverse cosecant of `z`. The result may be in radians or degrees depending on the current settings. acsc(z) is the same as asin(1/z). `z` may be any numeric expression that evaluates to a real number. This is the reverse of the `csc` function.

 Wikipedia MathWorld

acot function

Returns the inverse cotangent of the argument.

acot(z)

Description

The `acot` function calculates the inverse cotangent of `z`. The result may be in radians or degrees depending on the current settings. acot(z) is the same as atan(1/z). `z` may be any numeric expression that evaluates to a real number. This is the reverse of the `cot` function.

Remarks

The `acot` function returns a value in the range ]-π/2;π/2] (]-90;90] when calculating in degrees), which is the most common definition, though some may define it to be in the range ]0;π[.
