mathematics topics for competitive exams

  Hello guys, Welcome to all on my blog . I hope you are well and healthy. Today we teach all important math formulas  Which is used  in Mostly mathematics  Question. Here is list of mathematics formulae:✅✅ Content list:- Algebra formula Trigonometry formula                            Algebra                  1. (a²-b²) = (a + b)(a - b) 2. (a4- b4) = (a² + b²)(a² - b²) = (a² + b²)(a + b)(a - b) .3 (a + b + c)² = a² + b² + c² + 2(ab + bc + ca) 4.(a³-b³)= (a-b) (a²+ab+b²) 5. (a⁴-b⁴)=(a²+ b²+ ab)(a²+b²-ab)  1. (a + b)² a² + 2ab + b² 2. (a - b)² = a² - 2ab + b² Note: √a² - 2ab + b² when b > a. = (a - b) when a > band (b - a) 3. (a + b)² = (a - b)² + 4ab 4. (a - b)² = (a + b)²-4ab 5. (a + b)² + (a - b)² = 2(a² + b²) 6. (a + b)²-(a - b)² = 4ab 7. [(a+b)² + (a−b)²]/a²+b² = 2 8. [(a+b)²-(a−b)² ]/ ab = 4 9. (a + b)³ = a³ + b³ + 3ab(a + b) 10. (a - b)³ ...
