10x

Exponential (antilogarithm). Also accepts complex

 

 

numbers.

 

 

10^value

 

 

Example

 

 

10^3 returns 1000

 

 

Common logarithm. Also accepts complex numbers.

 

 

LOG(value)

 

 

Example

 

 

LOG(100) returns 2

,

,

Sine, cosine, tangent. Inputs and outputs depend on the

 

 

current angle format (Degrees, Radians, or Grads).

 

 

SIN(value)

 

 

COS(value)

 

 

TAN(value)

 

 

Example

 

 

TAN(45) returns 1 (Degrees mode).

 

ASIN

Arc sine: sin–1x.Output range is from –90° to 90°, –π/2

 

 

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

 

 

on the current angle format. Also accepts complex

 

 

numbers.

 

 

ASIN(value)

 

 

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).
