Returns the angle whose tangent is the quotient of two specified numbers. Logarithm the exponent or power to which a base must be raised to yield a given number. In other words it passes through 10 equals 1 when xa in other words it passes through a1 is an Injective one-to-one function.
Returns the smallest integral value thats greater than or equal to the specified Decimal or Double.
In general the logarithmic function. The natural logarithm of a number is its logarithm to the base of the mathematical constant e where e is an irrational and transcendental number approximately equal to 2718 281 828 459The natural logarithm of x is generally written as ln x log e x or sometimes if the base e is implicit simply log x. A logarithmic or log function is the inverse of an exponential function. Three kinds of functions that are often useful in mathematical models are linear functions exponential functions and logarithmic functions.
