# Thread: Equation Trigonometry

1. ## Equation Trigonometry

Solve the equation:
\sqrt[3]{cos5x +2cosx} - \sqrt[3]{2cos5x+cosx}=2\sqrt[3]{cosx}.(cos4x-cos2x)
Sorry but i can't for they in because it appear[LaTeX ERROR: Compile failed]

$\sqrt[3]{cos5x +2cosx} - \sqrt[3]{2cos5x+cosx}=2\sqrt[3]{cosx}.(cos4x-cos2x)$
