This formula provides two possible solutions for x, due to the ± sign. The part of the formula under the square root, b² - 4ac, is called the discriminant. The discriminant helps determine...
A complex number is generally expressed in the form a + bi, where 'a' and 'b' are real numbers, and 'i' is the imaginary unit (√-1). The 'a' part is the real part and 'b' is the imaginary part Complex...
Continuity And Differentiability : Bernard Bolzano first given the definition of continuity in 1817, after this Augustin-Louis Cauchy Defined continuity as an infinitely small increment of the independent...
In the context of JEE Main, "combinations" refer to the mathematical concept of selecting items from a set where the order of selection doesn't matter. The key formula is nCr = n! / (r! * (n-r)!),...
