Simplifying Cos(45 + x) = 0.42cos(45 + -1x) (45 * osC + x * osC) = 0.42cos(45 + -1x) (45osC + osxC) = 0.42cos(45 + -1x) 45osC + osxC = (45 * 0.42cos + -1x * 0.42cos) 45osC + osxC = (18.9cos + -0.42cosx) Solving 45osC + osxC = 18.9cos + -0.42cosx Solving for variable 'o'. Move all terms containing o to the left, all other terms to the right. Add '-18.9cos' to each side of the equation. 45osC + -18.9cos + osxC = 18.9cos + -18.9cos + -0.42cosx Reorder the terms: -18.9cos + 45osC + osxC = 18.9cos + -18.9cos + -0.42cosx Combine like terms: 18.9cos + -18.9cos = 0.0 -18.9cos + 45osC + osxC = 0.0 + -0.42cosx -18.9cos + 45osC + osxC = -0.42cosx Add '0.42cosx' to each side of the equation. -18.9cos + 45osC + 0.42cosx + osxC = -0.42cosx + 0.42cosx Reorder the terms: -18.9cos + 0.42cosx + 45osC + osxC = -0.42cosx + 0.42cosx Combine like terms: -0.42cosx + 0.42cosx = 0.00 -18.9cos + 0.42cosx + 45osC + osxC = 0.00 The solution to this equation could not be determined.
