Solution for sin(30+x)+cos(60+x)=cosx equation:


Simplifying
sin(30 + x) + cos(60 + x) = cosx
(30 * ins + x * ins) + cos(60 + x) = cosx
(30ins + insx) + cos(60 + x) = cosx
30ins + insx + (60 * cos + x * cos) = cosx
30ins + insx + (60cos + cosx) = cosx

Reorder the terms:
60cos + cosx + 30ins + insx = cosx

Add '-1cosx' to each side of the equation.
60cos + cosx + 30ins + -1cosx + insx = cosx + -1cosx

Reorder the terms:
60cos + cosx + -1cosx + 30ins + insx = cosx + -1cosx

Combine like terms: cosx + -1cosx = 0
60cos + 0 + 30ins + insx = cosx + -1cosx
60cos + 30ins + insx = cosx + -1cosx

Combine like terms: cosx + -1cosx = 0
60cos + 30ins + insx = 0

Solving
60cos + 30ins + insx = 0

Solving for variable 'c'.

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

Add '-30ins' to each side of the equation.
60cos + 30ins + -30ins + insx = 0 + -30ins

Combine like terms: 30ins + -30ins = 0
60cos + 0 + insx = 0 + -30ins
60cos + insx = 0 + -30ins
Remove the zero:
60cos + insx = -30ins

Add '-1insx' to each side of the equation.
60cos + insx + -1insx = -30ins + -1insx

Combine like terms: insx + -1insx = 0
60cos + 0 = -30ins + -1insx
60cos = -30ins + -1insx

Divide each side by '60os'.
c = -0.5ino-1 + -0.01666666667ino-1x

Simplifying
c = -0.5ino-1 + -0.01666666667ino-1x
