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))

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, 3 months 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.

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

cot A-cotB

=cosA/sinA  - cos B/sinB

=(sinBcosA-cosBsinA) /sinAsinB

=sin(B-A) / sinA sinB

d2= ((a+b)-(a-b))2 +((a-b)-(a+b))2

=(a+b-a+b)2 + (a-b-a-b)2

=4b2 + 4a2

so d= ((4(a2+b2))1/2

=2 root(a2+b2)

In calculus, Rolle's theorem or Rolle's lemma essentially states that any real-valued differentiable function that attains equal values at two distinct points must have at least one stationary point somewhere between them—that is, a point where the first derivative is zero.

In calculus, Rolle's theorem or Rolle's lemma essentially states that any real-valued differentiable function that attains equal values at two distinct points must have at least one stationary point somewhere between them—that is, a point where the first derivative (the slope of the tangent line to the graph of the function) is zero.
