Can you take the negative log of a negative number?

You can’t take the logarithm of a negative number or of zero. 2. The logarithm of a positive number may be negative or zero.

Is the log of a negative number imaginary?

is real.

How do you calculate negative log?

Calculating a negative log is as simple as using the formula x = Logb(1/a) , where x = -logb(a).

How do you find the negative log?

A common technique for handling negative values is to add a constant value to the data prior to applying the log transform. The transformation is therefore log(Y+a) where a is the constant. Some people like to choose a so that min(Y+a) is a very small positive number (like 0.001). Others choose a so that min(Y+a) = 1.

What is log of negative?

Natural Logarithm of Negative Number What is the natural logarithm of a negative number? The natural logarithm function ln(x) is defined only for x>0. So the natural logarithm of a negative number is undefined.

What is negative log equal to?

A negative logarithm means how many times to divide by the number. We can have just one divide: Example: What is log8(0.125)? Well, 1 ÷ 8 = 0.125, So log8(0.125) = −1.

How do you find the minus log?

Negative logarithm: It means the number of times we divide 1 by the base to achieve the log value. The negative of logy (x) is ylog (1 / x).

Can I find the natural log of a negative number?

What is the natural logarithm of a negative number? The natural logarithm function ln (x) is defined only for x>0. So the natural logarithm of a negative number is undefined. The complex logarithmic function Log (z) is defined for negative numbers too.

Can you take the natural log of a negative number?

If you are only working in real numbers, no, you cannot take the natural log of a negative number. If you are working in complex (imaginary) numbers, however, it is possible.

Can a negative number be greater than a positive number?

Explanation: It is impossible for a negative number to be greater than a positive number. All negatives are behind zero, therefore less than zero, on the number line, while all the positives are ahead of zero, meaning they’re greater than zero. In conclusion, a negative number is ALWAYS less than a positive number.

What is the natural logarithm of a negative number?

The natural logarithm can be defined for any positive real number a as the area under the curve y = 1/x from 1 to a (the area being taken as negative when a < 1).
