In symbols, log a6 = log a+log b. 2. The logarithm of a fraction is equal to the logarithm. of the numerator minus the logarithm of the denominator. In symbols, log T log a — = log h. 3. The logarithm of the reciprocal of a number is equal to. 4. The logarithm of a power is equal to the logarithm of the base multiplied by the exponent of the power,
Introduction to Logarithms - Math is Fun
In its simplest form, a logarithm answers the question: How many of one number multiply together to make another number? Example: How many 2 s multiply together to make 8? Answer: 2 × 2 × 2 = 8, so we had to multiply 3 of the 2 s to get 8. So the logarithm is 3. We write it like this: So these two things are the same:
List of trigonometric identities - Wikipedia
In trigonometry, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles.
