" 10."cos theta*cos2 theta*cos3 theta=(1)/(4)

Find all value of theta, between 0& pi, which satisfy the equation; cos theta*cos2 theta*cos3 theta=(1)/(4)

If cos2 theta*cos3 theta*cos theta=(1)/(4) for 0

Solve for theta,theta in[0,pi],cos theta cos2 theta cos3 theta=(1)/(4)

Solve the following equation: cos theta cos2 theta cos3 theta=(1)/(4)

Solve : cos theta cos 2 theta cos 3 theta =(1)/(4) (0 le theta le pi)

If theta=(pi)/(7), prove that cos theta cos2 theta cos3 theta=(1)/(2^(3))

Solve cos theta * cos 2 theta * cos 3 theta = (1)/( 4), 0 le theta le pi

Solve cos theta * cos 2 theta * cos 3 theta = (1)/( 4), 0 le theta le pi

Solve cos theta * cos 2 theta * cos 3 theta = (1)/( 4), 0 le theta le pi
