sin(x+0.3)+sin(x-0.3)=2cos(0.3)

Solution for sin(x+0.3)+sin(x-0.3)=2cos(0.3) equation:

Simplifying
sin(x + 0.3) + sin(x + -0.3) = 2cos(0.3)

Reorder the terms:
ins(0.3 + x) + sin(x + -0.3) = 2cos(0.3)
(0.3 * ins + x * ins) + sin(x + -0.3) = 2cos(0.3)
(0.3ins + insx) + sin(x + -0.3) = 2cos(0.3)

Reorder the terms:
0.3ins + insx + ins(-0.3 + x) = 2cos(0.3)
0.3ins + insx + (-0.3 * ins + x * ins) = 2cos(0.3)
0.3ins + insx + (-0.3ins + insx) = 2cos(0.3)

Reorder the terms:
0.3ins + -0.3ins + insx + insx = 2cos(0.3)

Combine like terms: 0.3ins + -0.3ins = 0.0
0.0 + insx + insx = 2cos(0.3)
insx + insx = 2cos(0.3)

Combine like terms: insx + insx = 2insx
2insx = 2cos(0.3)

Reorder the terms for easier multiplication:
2insx = 2 * 0.3cos

Multiply 2 * 0.3
2insx = 0.6cos

Solving
2insx = 0.6cos

Solving for variable 'i'.

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

Divide each side by '2nsx'.
i = 0.3cn-1ox-1

Simplifying
i = 0.3cn-1ox-1
