If `alpha, beta and gamma` are the angles which a directed line makes with the positive directions of the co-ordinates axes, then find the value of `sin^(2)alpha+sin^(2)beta+sin^(2)gamma`.

If alpha,beta,a n dgamma are the an gles which a directed line makes with the positive directions of the co-ordinates axes, then find the value of sin^2alpha+sin^2beta+sin^2gammadot

If alpha,beta,a n dgamma are the an gles which a directed line makes with the positive directions of the co-ordinates axes, then find the value of sin^2alpha+sin^2beta+sin^2gammadot

If a line makes angles alpha, beta, gamma when the positive direction of coordinates axes, then write the value of sin^(2) alpha + sin^(2) beta + sin^(2) gamma .

If a line makes angles alpha,beta,gamma with the positive direction of coordinate axes, then write the value of sin^2alpha+sin^2beta+sin^2gammadot

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

If alpha, beta, gamma are the angles which a line makes with positive direction of the axes, then match the quantities in column-I to their values in column-II:

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

If alpha,beta,gamma are the angle which a half ray makes with the positive direction of the axes then sin^2alpha+sin^2beta+sin^2gamma= (A) 1 (B) 2 (C) 0 (D) -1

If alpha, beta, gamma are the angles which a line makes with the coordinate axes ,then (A) sin^2alpha=cos^2beta+cos^2gamma (B) cos^2alpha+cos^2beta+cos^2gamma=2 (C) cos^2alpha+cos^2beta+cos^2gamma=1 (D) sin^2alpha+sin^2beta=1+cos^2gamma

If a line makes anles alpha, beta, gamma with the coordinate axes, porve that sin^2alpha+sin^2beta+sin^2gamma=2
