Solution for sinx-cos(x-20)=0 equation: 


Simplifying
sinx + -1cos(x + -20) = 0

Reorder the terms:
insx + -1cos(-20 + x) = 0
insx + (-20 * -1cos + x * -1cos) = 0
insx + (20cos + -1cosx) = 0

Reorder the terms:
20cos + -1cosx + insx = 0

Solving
20cos + -1cosx + insx = 0

Solving for variable 'c'.

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

Add '-1insx' to each side of the equation.
20cos + -1cosx + insx + -1insx = 0 + -1insx

Combine like terms: insx + -1insx = 0
20cos + -1cosx + 0 = 0 + -1insx
20cos + -1cosx = 0 + -1insx
Remove the zero:
20cos + -1cosx = -1insx

Combine like terms: -1insx + insx = 0
20cos + -1cosx + insx = 0

Factor out the Greatest Common Factor (GCF), 's'.
s(20co + -1cox + inx) = 0


Subproblem 1
