If a straight line makes angle a,b,c with coordinate axes respectively, then `sin^2a + sin^2b + sin^2c =`

If a line makes angles alpha , beta ,gamma with coordinate axes , then sin ^2 alpha +sin^2 beta + sin^2 gamma ………

If a line makes angle alpha, beta and gamma with the axes respectively then sin^(2)alpha+sin^(2)beta+sin^(2)gamma=

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

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 a line makes an angle alpha,beta,gamma with positive axes,then the range of sin alpha sin beta+sin beta sin gamma+sin gamma sin alpha is (A)(-(1)/(2),1) (B) ((1)/(2),2)(C)(-1,2)(D)(-1,2]

If a line in the space makes angle alpha,beta and gamma with the coordinate axes, then cos2alpha+cos2beta+cos2gamma+sin^2alpha+sin^2beta+sin^2gamma equals

If a,b, and c are the sides of a triangle and A,B and C are the angles opposite to a,b, and c, respectively,then a^(2)quad b sin A,c sin Ab=det[[b sin A,1,cos Ac sin A,cos A,1]]
