Logarithm of negative number The base b real logarithm of x when x<=0 is undefined when x is negative or equal to zero: log b ( x ) is undefined when x ≤ 0
5 Ιουν 2024 · Using this calculator, you can find the negative logarithm of any number with any chosen base. For details on logarithms and how to find the negative log of a number, read the description given below.
Raising the logarithm of a number to its base is equal to the number. Learn the eight (8) log rules or laws to help you evaluate, expand, condense, and solve logarithmic equations. Try out the log rules practice problems for an even better understanding.
29 Ιουλ 2024 · The key rules are as follows: product rule: which allows us to divide a product within a logarithm into a sum of separate logarithms; quotient rule: which allows us to divide a quotient within a logarithm into a difference of logarithms; power rule: which allows us to extract exponents from within a logarithm; base switch rule or change of base ...
11 Οκτ 2016 · The only numbers you can plug into a logarithm are positive numbers not equal to 1.
9 Ιαν 2017 · This is Euler's Formula, one of the most famous mathematical formula in history. Suddenly $e^z$ being a negative number is not impossible. But if $e^z$ is negative then we need to have $e^{z} = e^{a + bi} = e^a(\cos b + i \sin b)$ so $\cos b + i \sin b$ is a negative number.
The negative log of an argument is the logarithm of the reciprocal of the argument. i.e., -log b a = log b a -1 = log b (1/a). The negative log with a base is the logarithm whose base is the reciprocal of the given base. i.e., -log b a = log (1/b) a.
