If alpha , beta , gamma are the angles which a directed line makes with the positive directions of the co-ordinates axes,then sin^(2)alpha+sin^(2)beta+sin^(2)gamma is equal to

If alpha, beta, gamma are the angles made by a line with the positive directions of the coordinate axes, then sin^(2)alpha+sin^(2)beta+sin^(2)gamma=

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 be angles which a straighat line makes with the positive direction of the axes, then sin^2 alpha+sin^2beta+sin^2gamma is equal to (A) 4 (B) 1 (C) 2 (D) 3

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,a n dgamma are the angles 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 with the positive direction of coordinate axes,then write the value of sin^(2)alpha+sin^(2)beta+sin^(2)gamma
