Solution for Cos(2x+20)=sin(2x-10) equation:


Simplifying
Cos(2x + 20) = sin(2x + -10)

Reorder the terms:
osC(20 + 2x) = sin(2x + -10)
(20 * osC + 2x * osC) = sin(2x + -10)
(20osC + 2osxC) = sin(2x + -10)

Reorder the terms:
20osC + 2osxC = ins(-10 + 2x)
20osC + 2osxC = (-10 * ins + 2x * ins)
20osC + 2osxC = (-10ins + 2insx)

Solving
20osC + 2osxC = -10ins + 2insx

Solving for variable 'o'.

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

Reorder the terms:
10ins + -2insx + 20osC + 2osxC = -10ins + 2insx + 10ins + -2insx

Reorder the terms:
10ins + -2insx + 20osC + 2osxC = -10ins + 10ins + 2insx + -2insx

Combine like terms: -10ins + 10ins = 0
10ins + -2insx + 20osC + 2osxC = 0 + 2insx + -2insx
10ins + -2insx + 20osC + 2osxC = 2insx + -2insx

Combine like terms: 2insx + -2insx = 0
10ins + -2insx + 20osC + 2osxC = 0

Factor out the Greatest Common Factor (GCF), '2s'.
2s(5in + -1inx + 10oC + oxC) = 0

Ignore the factor 2.

Subproblem 1

Set the factor 's' equal to zero and attempt to solve: Simplifying s = 0 Solving s = 0 Move all terms containing o 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 '(5in + -1inx + 10oC + oxC)' equal to zero and attempt to solve: Simplifying 5in + -1inx + 10oC + oxC = 0 Solving 5in + -1inx + 10oC + oxC = 0 Move all terms containing o to the left, all other terms to the right. Add '-5in' to each side of the equation. 5in + -1inx + 10oC + -5in + oxC = 0 + -5in Reorder the terms: 5in + -5in + -1inx + 10oC + oxC = 0 + -5in Combine like terms: 5in + -5in = 0 0 + -1inx + 10oC + oxC = 0 + -5in -1inx + 10oC + oxC = 0 + -5in Remove the zero: -1inx + 10oC + oxC = -5in Add 'inx' to each side of the equation. -1inx + 10oC + inx + oxC = -5in + inx Reorder the terms: -1inx + inx + 10oC + oxC = -5in + inx Combine like terms: -1inx + inx = 0 0 + 10oC + oxC = -5in + inx 10oC + oxC = -5in + inx 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.
