0.56=-cos(y)

Solution for 0.56=-cos(y) equation:

Simplifying
0.56 = -1cos(y)

Multiply cos * y
0.56 = -1cosy

Solving
0.56 = -1cosy

Solving for variable 'c'.

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

Add 'cosy' to each side of the equation.
0.56 + cosy = -1cosy + cosy

Combine like terms: -1cosy + cosy = 0
0.56 + cosy = 0

Add '-0.56' to each side of the equation.
0.56 + -0.56 + cosy = 0 + -0.56

Combine like terms: 0.56 + -0.56 = 0.00
0.00 + cosy = 0 + -0.56
cosy = 0 + -0.56

Combine like terms: 0 + -0.56 = -0.56
cosy = -0.56

Divide each side by 'osy'.
c = -0.56o-1s-1y-1

Simplifying
c = -0.56o-1s-1y-1
