What are `alpha`,`beta` and` gamma` decays?

Give the characteristics of alpha, beta and gamma rays.

Derive the relation between alpha , beta , and gamma for a solid.

Distinguish between alpha rays and gamma rays .

If (secalpha+tanalpha)(secbeta+tanbeta)(secgamma+tangamma)=tanalphatanbetatangamma , then (secalpha-tanalpha)(secbeta-tanbeta)(secgamma-tangamma)= ........................ (A) cot alpha cot beta cot gamma (B) tan alpha tan beta tan gamma (C) cot alpha + cot beta + cot gamma (D) tan alpha +tan beta + tan gamma

If alpha+beta+gamma=2pi then

A line makes angles alpha,beta,gamma with co-ordinates axes. If alpha+beta=90^(@) then gamma is equal to

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 angles alpha,beta,gamma with co-ordinate axes, then cos2alpha+cos 2 beta+cos2gamma= a) -2 b) -1 c) 1 d) 2

If a line makes alpha,beta,gamma,delta angles with four diagonals of a cube, then cos2alpha+cos2beta+cos2gamma+cos2delta =
