Tap for more steps... x = 1.23095941 x = 1.23095941. The cosine function is positive in the first and fourth quadrants.Use the form asec(bx−c)+ d a sec ( b x - c) + d to find the variables used to find the amplitude, period, phase shift, and vertical shift. a = 1 a = 1. b = 1 b = 1. c = 0 c = 0. d = 0 d = 0. Since the graph of the function sec s e c does not have a maximum or minimum value, there can be no value for the amplitude. Amplitude: None. Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. Solve for ? cos (x)=1/2. cos (x) = 1 2 cos ( x) = 1 2. Take the inverse cosine of both sides of the equation to extract x x from inside the cosine. x = arccos(1 2) x = arccos ( 1 2) Simplify the right side. Tap for more steps... x = π 3 x = π 3. The cosine function is positive in the first and fourth quadrants.Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals.
