arcsin
Returns the arcus sine or inverse sine of a number x. The arcus sine is the angle whose sine evaluates to x. The result lies within a range of π/2 to π/2.
arcsinhyp
Returns the inverse hyperbolic sine of a number x. The inverse hyperbolic sine of x is the value whose hyperbolic sine evaluates to x.
arctan
Returns the arctangent of a number. The arctangent is the angle whose tangent is the argument. The returned angle is given in radians in the range π/2 to π/2.
arctanhyp
Returns the inverse hyperbolic tangent of x. The inverse hyperbolic tangent of x is the value whose hyperbolic tangent is x.
asin
Returns the arcus sine or inverse sine of a number x. The arcus sine is the angle whose sine evaluates to x. The result lies within a range of π/2 to π/2.
asinh
Returns the inverse hyperbolic sine of a number x. The inverse hyperbolic sine of x is the value whose hyperbolic sine evaluates to x.
atan
Returns the arctangent of a number. The arctangent is the angle whose tangent is the argument. The returned angle is given in radians in the range π/2 to π/2.
atanh
Returns the inverse hyperbolic tangent of x. The inverse hyperbolic tangent of x is the value whose hyperbolic tangent is x.
cos
Returns the cosine of the given angle.

x: is the angle in radians for which you want the cosine. If the angle is in degrees, multiply it by PI()/180 to convert it to radians.
cosh
Returns the hyperbolic cosine of a number.
coshyp
Returns the hyperbolic cosine of a number.
cot
Return the cotangent of an angle specified in radians.
coth
Return the hyperbolic cotangent of a hyperbolic angle.
cothyp
Return the hyperbolic cotangent of a hyperbolic angle.
e
Returns Euler's number (2.71....)
exp
Returns e raised to the power of number. The constant e equals 2.71828.... , the base of the natural logarithm.
ln
Returns the natural logarithm of a number. Natural logarithms are based on the constant e = 2.71828... . Ln() is the inverse of the exp() function.
log10
Returns the base10 logarithm of a number.
pi
Returns pi (3.14...)
pow
Returns the result of a number raised to a power.

x: is the base number. It can be any real number.

y: is the exponent to which the base number is raised.
rand
Returns a pseudorandom integer number.
randSeed
The rand function sets the starting point for generating a series of pseudorandom integers. To reinitialize the generator, use 1 as the seed argument. Any other value for seed sets the generator to a random starting point. rand retrieves the pseudorandom numbers that are generated. Calling rand with no seed before any call to rand with a seed generates the same sequence as calling rand with seed 1.
round
rounds floating point numbers to a specified number of digits
sgn
Determines the sign of a number. Returns 1 if the number is positive, zero (0) if the number is 0, and 1 if the number is negative.
sin
Returns the sine of the given angle.

x: is the angle in radians for which you want the sine. If your argument is in degrees, multiply it by PI()/180 to convert it to radians.
sinh
Returns the hyperbolic sine of a number.
sinhyp
Returns the hyperbolic sine of a number.
sqr
Returns a positive square root.

x: is the number for which you want the square root. If number is negative, the function will return an error value.
tan
Returns the tangent of the given angle.

x: is the angle in radians for which you want the tangent. If your argument is in degrees, multiply it by PI()/180 to convert it to radians.
tanh
Returns the hyperbolic tangent of a number.
tanhyp
Returns the hyperbolic tangent of a number.
