Solution for sin(x+10)=cos(40+x) equation:


Simplifying
sin(x + 10) = cos(40 + x)

Reorder the terms:
ins(10 + x) = cos(40 + x)
(10 * ins + x * ins) = cos(40 + x)
(10ins + insx) = cos(40 + x)
10ins + insx = (40 * cos + x * cos)
10ins + insx = (40cos + cosx)

Solving
10ins + insx = 40cos + cosx

Solving for variable 'i'.

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

Reorder the terms:
-40cos + -1cosx + 10ins + insx = 40cos + cosx + -40cos + -1cosx

Reorder the terms:
-40cos + -1cosx + 10ins + insx = 40cos + -40cos + cosx + -1cosx

Combine like terms: 40cos + -40cos = 0
-40cos + -1cosx + 10ins + insx = 0 + cosx + -1cosx
-40cos + -1cosx + 10ins + insx = cosx + -1cosx

Combine like terms: cosx + -1cosx = 0
-40cos + -1cosx + 10ins + insx = 0

Factor out the Greatest Common Factor (GCF), 's'.
s(-40co + -1cox + 10in + inx) = 0

Subproblem 1

Set the factor 's' equal to zero and attempt to solve: Simplifying s = 0 Solving s = 0 Move all terms containing i to the left, all other terms to the right. Add '-1s' to each side of the equation. s + -1s = 0 + -1s Remove the zero: 0 = -1s Simplifying 0 = -1s 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 '(-40co + -1cox + 10in + inx)' equal to zero and attempt to solve: Simplifying -40co + -1cox + 10in + inx = 0 Solving -40co + -1cox + 10in + inx = 0 Move all terms containing i to the left, all other terms to the right. Add '40co' to each side of the equation. -40co + -1cox + 10in + 40co + inx = 0 + 40co Reorder the terms: -40co + 40co + -1cox + 10in + inx = 0 + 40co Combine like terms: -40co + 40co = 0 0 + -1cox + 10in + inx = 0 + 40co -1cox + 10in + inx = 0 + 40co Remove the zero: -1cox + 10in + inx = 40co Add 'cox' to each side of the equation. -1cox + 10in + cox + inx = 40co + cox Reorder the terms: -1cox + cox + 10in + inx = 40co + cox Combine like terms: -1cox + cox = 0 0 + 10in + inx = 40co + cox 10in + inx = 40co + cox 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.
