Simplifying cos(3x + 30) = 0.5 Reorder the terms: cos(30 + 3x) = 0.5 (30 * cos + 3x * cos) = 0.5 (30cos + 3cosx) = 0.5 Solving 30cos + 3cosx = 0.5 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Reorder the terms: -0.5 + 30cos + 3cosx = 0.5 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 -0.5 + 30cos + 3cosx = 0.0 The solution to this equation could not be determined.
