sin(z)

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.

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

cos(z)

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.

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

tan(z)

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.

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(z)

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(z)

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.

atan(z)

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.

sec(z)

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.

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

csc(z)

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.

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

cot(z)

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.

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

asec(z)

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.

acsc(z)

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.

acot(z)

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.

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[.
