Cos of 2 theta
Webcos 2x = cos^2 x - sin^2 x Makes sense, because that's the way you would get it if you applied the rule of adding 2 different angles. How do you get from there to what they … 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 4 Similar questions Q.
