WebFree math problem solver answers your trigonometry homework questions with step-by-step explanations. WebExplanation for the correct option: We know that the range of a cos θ + b sin θ is - ( a 2 + b 2), ( a 2 + b 2). So, the maximum value of a cos x + b sin x is ( a 2 + b 2). For example, the maximum value of 3 cos θ + 4 sin θ is given as: Now, placing a = 3, b = 4 in ( a 2 + b 2), we get, = ( 3 2 + 4 2) = 9 + 16 = 25 = 5
