WebA standard method of evaluating the secant integral presented in various references involves multiplying the numerator and denominator by sec θ + tan θ and then using the substitution u = sec θ + tan θ. This substitution can be obtained from the derivatives of secant and tangent added together, which have secant as a common factor. WebWe can read trigonometric definitions right from the triangle as corresponding ratios of sides. Specifically, for angle θ, tan θ = y x, and sec θ = r x. We can now write, 1 + tan 2 θ = …

WebSolve your math problems using our free math solver with step-by-step solutions. Our math solver supports basic math, pre-algebra, algebra, trigonometry, calculus and more. Web7 years ago. The easiest way is to see that cos 2φ = cos²φ - sin²φ = 2 cos²φ - 1 or 1 - 2sin²φ by the cosine double angle formula and the Pythagorean identity. Now substitute 2φ = θ into those last two equations and solve for sin θ/2 and cos θ/2. WebHere is a simpler solution to this problem: (sec(θ)+tan(θ))(sec(θ)−tan(θ)) = sec2(θ)−tan2(θ) = 1 Since sec(θ)+ tan(θ) = 5 you ...
