quick problem-solving in JEE Main and Advanced for Mathematics Memorizing key formulas

  Memorizing key formulas is essential for quick problem-solving in JEE Main and Advanced. Here are some important formulas across various topics in Mathematics: Algebra Quadratic Equations : Roots:  x = − b ± b 2 − 4 a c 2 a x = 2 a − b ± b 2 − 4 a c ​ ​ Sum of roots:  α + β = − b a α + β = − a b ​ Product of roots:  α β = c a α β = a c ​ Sequences and Series : n n -th term of an AP:  a n = a + ( n − 1 ) d a n ​ = a + ( n − 1 ) d Sum of first  n n  terms of an AP:  S n = n 2 [ 2 a + ( n − 1 ) d ] S n ​ = 2 n ​ [ 2 a + ( n − 1 ) d ] n n -th term of a GP:  a n = a r n − 1 a n ​ = a r n − 1 Sum of first  n n  terms of a GP:  S n = a r n − 1 r − 1 S n ​ = a r − 1 r n − 1 ​  (for  r ≠ 1 r  = 1 ) Complex Numbers : z = a + b i z = a + bi Modulus:  ∣ z ∣ = a 2 + b 2 ∣ z ∣ = a 2 + b 2 ​ Argument:  arg ⁡ ( z ) = tan ⁡ − 1 ( b a ) ar g ( z ) = tan − 1 ( a b ​ ) Binomial Theorem : ( a + b ) n = ∑ k = 0 n ( n k ) a n −...
