Negatives cause no problem: log10x = -3 means x = 10-3 = 0.001 It doesn't make sense, though, to FIND the logarithm of a negative number: log10(-8) = ???? (unless you know about complex numbers . . . )

What does trigonometry involve?
You need to be able to solve logarithms and be very good at algebra. In college, you have to be able to do college level algebra before you can take trig.
Rule for multiplying integers?
Positive x negative = negative (Negative x positive = negative) Positive x positive = positive Negative x negative = positive So if the signs are the same the answer is positive and if they are different it is negative.
Is Sin a negative function or positive?
negative
What does negative sine squared plus cosine squared equal?
To determine what negative sine squared plus cosine squared is equal to, start with the primary trigonometric identity, which is based on the pythagorean theorem...sin2(theta) + cos2(theta) = 1... and then solve for the question...cos2(theta) = 1 - sin2(theta)2 cos2(theta) = 1 - sin2(theta) + cos2(theta)2 cos2(theta) - 1 = - sin2(theta) + cos2(theta)
How do you solve absolute value inequalities?
The absolute value of something is also the square root of the square of that something. This can be used to solve equations involving absolute values.
When does Exponents used to solve a math problem?
common logarithms, natural logarithms, monatary calculations, etc.
How do you solve logarithms of numbers less than one?
33
What is the logarithm of -1?
Negative numbers don't have logarithms.
Is there a negative answer on logarithm?
Logarithms of numbers less than one are negative. For example, the logarithm of 1/2 will be negative.
What should you include in a paper about Logarithms?
you should include the definition of logarithms how to solve logarithmic equations how they are used in applications of math and everyday life how to graph logarithms explain how logarithms are the inverses of exponential how to graph exponentials importance of exponential functions(growth and decay ex.) pandemics, population)
What is logarithm of log -2?
There is no answer. Logarithms operate only on non-negative numbers. * * * * * Actually, logarithms are not defined for 0 either, so they operate only on positive numbers.
How do you solve 5 times 186x equals 26 using exponential equations with logarithms?
that is supposes to be 18 to the 6x power
What is the value of 0.05555 divide by 0.0008601 if use logarithms to solve the problem?
64.5855
How do you solve logarithmic simultaneous equations?
That would depend a lot on the specific equations. Often the following tricks can help: (a) Take antilogarithms to get rid of the logarithms. (b) Use the properties of logarithms, especially: log(ab) = log a + log b; log(a/b) = log a - log b; log ab = b log a. (These properties work for logarithms in any base.)
What does trigonometry involve?
You need to be able to solve logarithms and be very good at algebra. In college, you have to be able to do college level algebra before you can take trig.
What is the log of -123?
Within the real numbers, logarithms of zero and negative numbers are not defined. If you are interested in calculating logarithms within the complex number system, the Wikipedia article on "logarithm" has the necessary formulae. In this case, you can obtain the logarithm of a negative number, but not of zero.
The base of common logarithms?
The base of common logarithms is ten.
