Mathematics Formulas
Formulas for Basic mathematics (a+b)^2 = a^2 + 2ab + b^2 Detailed Understandings (a+b) * (a+b) a*a + a*b + b*a + b*b a^2 + 2ab + b^2 (a-b)^2 = a^2 - 2ab + b^2 Detailed Understandings (a-b) * (a-b) a*a - a*b - b*a + b*b a^2 - 2ab + b^2 (a+b)^3 = a^3 + b^3 + 3ab(a+b) Detailed Understandings (a+b)*(a+b)*(a+b) (a^2 + 2ab + b^2)* (a+b) >> Using (a+b)^2 formula a3 + 2a^2b + ab^2 + ba^2 + 2ab^2 + b^3 a^3 + b^3 + 3a^2b + 3ab^2 + b^3 a^3 + b^3 + 3ab(a+b) How a^0 = 1 is derived? a^0 1) a^(1-1) a^1 / a^1 = 1 Hence this is derived a^0 = 1
