WebThe trigonometric triple-angle identities give a relationship between the basic trigonometric functions applied to three times an angle in terms of trigonometric functions of the angle itself.. Triple-angle Identities \[ \sin 3 \theta = 3 \sin \theta - 4 \sin ^3 \theta \] \[ \cos 3\theta = 4 \cos ^ 3 \theta - 3 \cos \theta \] WebCalculus. Find the Integral cos (theta)^2. cos2 (θ) cos 2 ( θ) Use the half - angle formula to rewrite cos2(θ) cos 2 ( θ) as 1+cos(2θ) 2 1 + cos ( 2 θ) 2. ∫ 1+cos(2θ) 2 dθ ∫ 1 + cos ( 2 θ) 2 d θ. Since 1 2 1 2 is constant with respect to θ θ, move 1 2 1 2 out of the integral. 1 2 ∫ 1+cos(2θ)dθ 1 2 ∫ 1 + cos ( 2 θ) d θ.
http://www.math.com/tables/trig/identities.htm WebWe know that the maximum value of a cos θ + b sin θ + c is c + ( a 2 + b 2). Substituting a = 13 2, b = - 3 √ 3 2 and c = 3, we get, The maximum value = 3 + 169 4 + 27 4 = 3 + 7 = 10. Hence, Option ( C) is the correct answer. Suggest Corrections.
