Any Formulas In the Mathematics
Thursday, 12 may 2016 7 : 39 pm. Good Night everyone !!!!!!!, in this night i want make some post about formulas math, here the list of the formula. It's not too much but i think it can help us to study better about math. Anyway, i have file 1300 formulas of math, i will upload it soon !.
a^{ 2}  b^{ 2} = (a+b)(ab) (Difference of squares)
a^{ 3} b^{ 3} = (a b)(a^{ 2} ab + b^{ 2}) (Sum and Difference of Cubes)
x^{ 2} + (a+b)x + AB = (x + a)(x + b)
if ax^{ 2} + bx + c = 0 then x = ( b (b^{ 2}  4ac) ) / 2a (Quadratic Formula)
a+b)^{ 2} = a^{ 2} + 2ab + b^{ 2}
(a+b)(c+d) = ac + ad + bc + bda^{ 2}  b^{ 2} = (a+b)(ab) (Difference of squares)
a^{ 3} b^{ 3} = (a b)(a^{ 2} ab + b^{ 2}) (Sum and Difference of Cubes)
x^{ 2} + (a+b)x + AB = (x + a)(x + b)
if ax^{ 2} + bx + c = 0 then x = ( b (b^{ 2}  4ac) ) / 2a (Quadratic Formula)
Powersx^{ a} x^{ b} = x^{ (a + b)}x^{ a} y^{ a} = (xy)^{ a}(x^{ a})^{ b} = x^{ (ab)} x^{ (a/b)} = b^{th} root of (x^{ a}) = ( b^{th} (x) )^{ a} x^{ (a)} = 1 / x^{ a} x^{ (a  b)} = x^{ a} / x^{ b} Logarithmsy = log_{b}(x) if and only if x=b^{ y}log_{b}(1) = 0log_{b}(b) = 1 log_{b}(x*y) = log_{b}(x) + log_{b}(y) log_{b}(x/y) = log_{b}(x)  log_{b}(y) log_{b}(x^{ n}) = n log_{b}(x)log_{b}(x) = log_{b}(c) * log_{c}(x) = log_{c}(x) / log_{c}(b)
