The locus of the point (r cos alpha cos beta, r cos alpha sin beta, r sin alpha) is

Evaluate {:[( cos alpha cos beta , cos alpha sin beta , -sin alpha ),( -sin beta , cos beta, 0),( sin alpha cos beta, sin alpha sin beta, cos alpha ) ]:} =0

If 3sin beta = sin(2alpha + beta) , then tan(alpha + beta)-2tan alpha is:

(sec alpha * sec beta + tan alpha tan beta )^(2)-( sec alpha * tan beta + tan alpha * sec beta )^(2) =

(i) sin (alpha + beta) = sin alpha cos beta + cos alpha sin beta) (ii) sin (alpha-beta)= sin alpha cos beta- cos alpha sin beta Proof

If sin beta=sin(2alpha+beta) , then tan(alpha+beta)-2tan alpha is

If alpha,beta are acute angles, sin alpha = (4)/(5), tan beta = (5)/(12) then the descending order of A= sin (alpha+beta), B cos(alpha+beta),C= tan(alpha+beta) is
