Trigonometric Functions

The trigonometric functions take radians as arguments.

Numbers provides these trigonometric functions.

Returns 1 when the argument is positive, –1 when the argument is 
negative, and 0 when it’s zero.

SQRT (page 274)

Calculates the square root of a number.

Calculates the sum of a set of numbers.

SUMIF (page 278)

Calculates the sum of a set of numbers that satisfy a specified 
condition.

SUMPRODUCT (page 278)

Calculates the sum of the products of corresponding numbers in 
two or more ranges.

Calculates the sum of the squares of a set of numbers.

Truncates a decimal number to a specified number of digits.

ACOS (page 206)

Calculates the inverse cosine (arccosine) in the range 0 to pi 
radians.

ACOSH (page 207)
