Solution for F(x)=4cos(3x^2) equation:


Simplifying
F(x) = 4cos(3x2)

Multiply F * x
xF = 4cos(3x2)

Remove parenthesis around (3x2)
xF = 4cos * 3x2

Reorder the terms for easier multiplication:
xF = 4 * 3cos * x2

Multiply 4 * 3
xF = 12cos * x2

Multiply cos * x2
xF = 12cosx2

Solving
xF = 12cosx2

Solving for variable 'x'.

Reorder the terms:
-12cosx2 + xF = 12cosx2 + -12cosx2

Combine like terms: 12cosx2 + -12cosx2 = 0
-12cosx2 + xF = 0

Factor out the Greatest Common Factor (GCF), 'x'.
x(-12cosx + F) = 0

Subproblem 1

Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0

Subproblem 2

Set the factor '(-12cosx + F)' equal to zero and attempt to solve: Simplifying -12cosx + F = 0 Reorder the terms: F + -12cosx = 0 Solving F + -12cosx = 0 Move all terms containing x to the left, all other terms to the right. Add '-1F' to each side of the equation. F + -1F + -12cosx = 0 + -1F Combine like terms: F + -1F = 0 0 + -12cosx = 0 + -1F -12cosx = 0 + -1F Remove the zero: -12cosx = -1F Divide each side by '-12cos'. x = 0.08333333333c-1o-1s-1F Simplifying x = 0.08333333333c-1o-1s-1F

Solution

x = {0, 0.08333333333c-1o-1s-1F}
