Symbol Description Example
sin
cos
tan
Sine, cosine, tangent - trigonometric functions
The angle value in degrees is indicated in brackets
Sin(30) = 0.5
Cos(180) = -1
Tan(45) = 1
EXP Exhibitor. Means "10 ^" or "... times ten to the power ..." 1 x 10^1 = 10
5 x 10^0 = 5
% Percent. Converts a number, represented as a percentage, to an absolute numeric value. 60% = 0.6
20 x 5% = 1
π ('pi') A mathematical constant equal to the ratio of the circumference of a circle to its diameter. It is designated by the letter of the Greek alphabet "π". π = 3.1415926536
2π x 10 = 62.831853072
e Mathematical constant, irrational and transcendental number. Approximately 2.71828. Sometimes called Euler's number or Napier's number. It is designated by the lowercase Latin letter "e". e = 2.7182818285
ln The base of the logarithm is e, where e is an irrational constant. The natural logarithm of x is the exponent to which e must be raised to get x ln(e) = 1
ln(1) = 0
log The decimal logarithm is the base 10 logarithm. In other words, the decimal logarithm of b is the solution to the equation 10 ^ x = b log(10) = 1
log(1000) = 3
! The factorial of a number n is the product of all natural numbers less than or equal to x n. The factorial is denoted by n! = 1x2x3x ... (n-1) n 1! = 1
5! = 120
The square root is a number equal to the radical expression to the second power √(9) = 3
√(0) = 0
xⁿ The power of a number a with natural exponent n is an expression of the form an, the value of which is equal to the product of n factors, each of which is equal to a 100^0 = 1
2^10 = 1024
The square of a number is the result of multiplying the number by itself. In addition, the square of a number is the result of raising the number to the power of 2 (to the second power). 8² = 64
0² = 0
|x| The modulus of a number is the absolute value of a number. An absolute value is a non-negative number that satisfies the conditions:
| x | = x if x ⩾ 0
| x | = -x if x < 0
|10| = 10
|-10| = 10
