Solution for 0=7cos(8x+1) equation:


Simplifying
0 = 7cos(8x + 1)

Reorder the terms:
0 = 7cos(1 + 8x)
0 = (1 * 7cos + 8x * 7cos)
0 = (7cos + 56cosx)

Solving
0 = 7cos + 56cosx

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '-7cos' to each side of the equation.
0 + -7cos = 7cos + -7cos + 56cosx
Remove the zero:
-7cos = 7cos + -7cos + 56cosx

Combine like terms: 7cos + -7cos = 0
-7cos = 0 + 56cosx
-7cos = 56cosx

Add '-56cosx' to each side of the equation.
-7cos + -56cosx = 56cosx + -56cosx

Combine like terms: 56cosx + -56cosx = 0
-7cos + -56cosx = 0

Factor out the Greatest Common Factor (GCF), '-7cos'.
-7cos(1 + 8x) = 0

Ignore the factor -7.

Subproblem 1

Set the factor 'cos' equal to zero and attempt to solve: Simplifying cos = 0 Solving cos = 0 Move all terms containing c to the left, all other terms to the right. Simplifying cos = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(1 + 8x)' equal to zero and attempt to solve: Simplifying 1 + 8x = 0 Solving 1 + 8x = 0 Move all terms containing c to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + 8x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 8x = 0 + -1 8x = 0 + -1 Combine like terms: 0 + -1 = -1 8x = -1 Add '-8x' to each side of the equation. 8x + -8x = -1 + -8x Combine like terms: 8x + -8x = 0 0 = -1 + -8x Simplifying 0 = -1 + -8x The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
