An iden.y cannot be 'solved ' in the way an equation can because it is true for all values of the variable - which is not very helpful if one is lo.ng for a particular solution. Iden.ies are very useful when it is desirable to express an alge.ic statement in an alternative but equally true form..

  • Iden Y Mathematics Wikipedia

    Several important formulas, sometimesed logarithmic iden.ies or log laws, relate logarithms to one another Product, quotient, power and root. The logarithm of a product is the sum of the logarithms of the numbers being multiplied; the logarithm of the ratio of two numbers is the difference of the logarithms..
