Solution for 4sin(2x+10)=6cos(2x+10) equation:


Simplifying
4sin(2x + 10) = 6cos(2x + 10)

Reorder the terms:
4ins(10 + 2x) = 6cos(2x + 10)
(10 * 4ins + 2x * 4ins) = 6cos(2x + 10)
(40ins + 8insx) = 6cos(2x + 10)

Reorder the terms:
40ins + 8insx = 6cos(10 + 2x)
40ins + 8insx = (10 * 6cos + 2x * 6cos)
40ins + 8insx = (60cos + 12cosx)

Solving
40ins + 8insx = 60cos + 12cosx

Solving for variable 'i'.

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

Reorder the terms:
-60cos + -12cosx + 40ins + 8insx = 60cos + 12cosx + -60cos + -12cosx

Reorder the terms:
-60cos + -12cosx + 40ins + 8insx = 60cos + -60cos + 12cosx + -12cosx

Combine like terms: 60cos + -60cos = 0
-60cos + -12cosx + 40ins + 8insx = 0 + 12cosx + -12cosx
-60cos + -12cosx + 40ins + 8insx = 12cosx + -12cosx

Combine like terms: 12cosx + -12cosx = 0
-60cos + -12cosx + 40ins + 8insx = 0

Factor out the Greatest Common Factor (GCF), '4s'.
4s(-15co + -3cox + 10in + 2inx) = 0

Ignore the factor 4.

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 '(-15co + -3cox + 10in + 2inx)' equal to zero and attempt to solve: Simplifying -15co + -3cox + 10in + 2inx = 0 Solving -15co + -3cox + 10in + 2inx = 0 Move all terms containing i to the left, all other terms to the right. Add '15co' to each side of the equation. -15co + -3cox + 10in + 15co + 2inx = 0 + 15co Reorder the terms: -15co + 15co + -3cox + 10in + 2inx = 0 + 15co Combine like terms: -15co + 15co = 0 0 + -3cox + 10in + 2inx = 0 + 15co -3cox + 10in + 2inx = 0 + 15co Remove the zero: -3cox + 10in + 2inx = 15co Add '3cox' to each side of the equation. -3cox + 10in + 3cox + 2inx = 15co + 3cox Reorder the terms: -3cox + 3cox + 10in + 2inx = 15co + 3cox Combine like terms: -3cox + 3cox = 0 0 + 10in + 2inx = 15co + 3cox 10in + 2inx = 15co + 3cox 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.
