Example

 

ASIN(1) returns 90 (Degrees mode).

ACOS

Arc cosine: cos–1x. Output range is from 0° to 180°, 0 to

 

π, or 0 to 200 grads. Inputs and outputs depend on the

 

current angle format. Also accepts complex numbers.

 

Output will be complex for values outside the normal

 

COS domain of –1 ≤ x ≤ 1 .

 

ACOS(value)

 

Example

 

ACOS(1) returns 0 (Degrees mode).

ATAN

Arc tangent: tan–1x. Output range is from –90° to 90°,

 

2π/2 to π/2, or –100 to 100 grads. Inputs and outputs

 

depend on the current angle format. Also accepts

 

complex numbers.

 

ATAN(value)

 

Example

 

ATAN(1) returns 45 (Degrees mode).

 

Square. Also accepts complex numbers.

 

value2

 

Example

 

182 returns 324

 

Square root. Also accepts complex numbers.

 

 

value

 

Example

 

 

 

returns 18

 

 

324

 

Negation. Also accepts complex numbers.

 

–value

 

Example

 

-(1,2) returns (-1,-2)

 

Power (x raised to y). Also accepts complex numbers.
