Let alpha, beta, gamma be the angles made by a line with the positive directions of the axes of reference in three dimensions. If theta is the acute angle given by costheta=(cos^(2)alpha+cos^(2)beta+cos^(2)gamma)/(sin^(2)alpha+sin^(2)beta+sin^(2)gamma) , then theta equal.

If alpha, beta , gamma are the angles that a line makes with the positive direction of x, y, z axis, respectively, then the direction-cosines of the line are :

If alpha, beta and gamma are angles made by the line with positive direction direction of X-axis, Y-axis and Z-axis respectively, then find the value of cos2alpha+cos2beta+cos2gamma .

If theta is an angle given by cos theta = (cos ^(2) alpha + cos ^(2) beta + cos ^(2) gamma)/( sin ^(2) alpha + sin ^(2) beta + sin ^(2) gamma) where alpha, beta, gamma are the equal angles made by line with the positive directions of the axes, then the measure of theta is

If alpha,beta,gamma be the angles which a line makes with the coordinates axes, then

If alpha and beta are two positive acute angles satisfying alpha-beta=15^(@) and sin alpha=cos2 beta then the value of alpha+beta

If sin (alpha - beta) =1/2 and cos (alpha + beta) =1/2, where alpha and beta are positive acute angles, then alpha and beta are
