Chain rule is defined as: The composition [katex]fog[/katex] of function [katex]f[/katex] and [katex]g[/katex] is the function whose value [katex]f[g(x)][/katex] are found for […]

Product Rule of Derivatives:If [katex]f[/katex] and [katex]g[/katex] are differentiable at [katex]x[/katex], then [katex]f_g[/katex] is also differentiable at [katex]x[/katex] and [katex]\lbrack f(x)g(x)\rbrack’=f(x)g'(x)+f'(x)g(x)[/katex]. [katex]i.e,\;\;\;\;\;\frac […]

Quadratic Formula Derivation: Again there are some quadratic polynomials that are not factorable at all using integral coefficients. In such a case […]

Quadratic Equation definition: A quadratic equation in [katex]x[/katex] is an equation that can be written in the form of [katex]a\;x^2-bx+c=0\;\;\;\;\;\;\;\;\;\;\;\;\;;a,\;b,\;c [/katex] are […]
