Vector p makes an angle ,a,b,g with the X,Y,Z axes respectively then Sina*Sina+sinb*sinb+sing*sing =?

Question

sonika p · Answer

since p makes an angle ,a,b,g with the X,Y,Z axes respectively, cosa, cosb, cosg are known as direction cosines of p, where, cos 2 a + cos 2 b + cos 2 g =1 1-sin 2 a + 1-sin 2 b + 1-sin 2 g = 1 3 – sin 2 a – sin 2 b – sin 2 g =1 sin 2 a + sin 2 b + sin 2 g =2
