Harsh Mishra 7 years, 1 month ago

The differentiation of sec {tan root( x )} is ? as given: Answer, y'=sec(tan(x))tan(tan(x))(sec2(x)) Solution : If, y=sec(f(x)) then using chain rule, y'=sec(f(x))tan(f(x))f'(x) In same way, y'=sec(tan(x))tan(tan(x))(tan(x)) ' y' =sec(tan(x))tan(tan(x))(sec2(x))

R D Sharma is best book for maths

Ayushi Ayushi 7 years, 1 month ago

For your knowledge - The rule is named after the 17th-century French mathematician Guillaume de l'Hôpital. Although the contribution of the rule is often attributed to L'Hôpital, the theorem was first introduced to L'Hôpital in 1694 by the Swiss mathematician Johann Bernoulli.

Ayushi Ayushi 7 years, 1 month ago

In mathematics, and more specifically in calculus, L'Hôpital's rule or L'Hospital's rule (French: [lopital]) uses derivatives to help evaluate limits involving indeterminate forms. Application (or repeated application) of the rule often converts an indeterminate form to an expression that can be evaluated by substitution, allowing easier evaluation of the limit.

Helly Patel 7 years, 1 month ago

Here, tanA =a/a+1. And. TanB = 1/2a+1 A = tan–¹(a/a+1) B = tan –¹(1/2a+1) A+B = tan–¹(a/a+1) + tan–¹ (1/2a+1) = tan–¹[(a/a+1) + (1/2a+1) / 1 - (a/a+1)(1/2a+1)] = tan–¹(2a²+2a+1/2a²+2a+1) = tan –¹(1) = tan–¹[tan(π/4)] =π/4
