Find all solutions of the equation in the interval...

Find all solutions of the equation in the interval \( [ 0,2 \pi ) \) 

\( \cos 5 x \cos 2 x + \sin 5 x \sin 2 x = 0\)

Write your answer in radians in terms of \( \pi \) . If there is more than one solution, separate them with commas. 

Answer

cos3x=0

x=\(\frac{pi}{6}\) x=\(\frac{pi}{2}\) x=\(\frac{5pi}{6}\) x=\(\frac{7pi}{6}\) x=\(\frac{3pi}{2}\) x=\(\frac{11pi}{6}\)
