Solution for cos(x+70)cox(x+10)=0.5 equation:


Simplifying
cos(x + 70) * cox(x + 10) = 0.5

Reorder the terms:
cos(70 + x) * cox(x + 10) = 0.5

Reorder the terms:
cos(70 + x) * cox(10 + x) = 0.5

Reorder the terms for easier multiplication:
cos * cox(70 + x)(10 + x) = 0.5

Multiply cos * cox
c2o2sx(70 + x)(10 + x) = 0.5

Multiply (70 + x) * (10 + x)
c2o2sx(70(10 + x) + x(10 + x)) = 0.5
c2o2sx((10 * 70 + x * 70) + x(10 + x)) = 0.5
c2o2sx((700 + 70x) + x(10 + x)) = 0.5
c2o2sx(700 + 70x + (10 * x + x * x)) = 0.5
c2o2sx(700 + 70x + (10x + x2)) = 0.5

Combine like terms: 70x + 10x = 80x
c2o2sx(700 + 80x + x2) = 0.5
(700 * c2o2sx + 80x * c2o2sx + x2 * c2o2sx) = 0.5
(700c2o2sx + 80c2o2sx2 + c2o2sx3) = 0.5

Solving
700c2o2sx + 80c2o2sx2 + c2o2sx3 = 0.5

Solving for variable 'c'.

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

Reorder the terms:
-0.5 + 700c2o2sx + 80c2o2sx2 + c2o2sx3 = 0.5 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
-0.5 + 700c2o2sx + 80c2o2sx2 + c2o2sx3 = 0.0
