WebSo let's do it. So we know the Pythagorean identity, sine squared theta, plus cosine squared theta is equal to 1. We know what sine squared theta is. Sine theta is 1/2. So this could be rewritten as 1/2 squared, plus cosine squared theta, is equal to 1. Or we could write this as 1/4 plus cosine squared theta is equal to 1. 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.
