1=cos(x+1.57)

Solution for 1=cos(x+1.57) equation:

Simplifying
1 = cos(x + 1.57)

Reorder the terms:
1 = cos(1.57 + x)
1 = (1.57 * cos + x * cos)
1 = (1.57cos + cosx)

Solving
1 = 1.57cos + cosx

Solving for variable 'c'.

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

Add '-1.57cos' to each side of the equation.
1 + -1.57cos = 1.57cos + -1.57cos + cosx

Combine like terms: 1.57cos + -1.57cos = 0.00
1 + -1.57cos = 0.00 + cosx
1 + -1.57cos = cosx

Add '-1cosx' to each side of the equation.
1 + -1.57cos + -1cosx = cosx + -1cosx

Combine like terms: cosx + -1cosx = 0
1 + -1.57cos + -1cosx = 0

Add '-1' to each side of the equation.
1 + -1.57cos + -1 + -1cosx = 0 + -1

Reorder the terms:
1 + -1 + -1.57cos + -1cosx = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -1.57cos + -1cosx = 0 + -1
-1.57cos + -1cosx = 0 + -1

Combine like terms: 0 + -1 = -1
-1.57cos + -1cosx = -1

Reorder the terms:
1 + -1.57cos + -1cosx = -1 + 1

Combine like terms: -1 + 1 = 0
1 + -1.57cos + -1cosx = 0
