1. Find the distance between the following points.(i) (a cos `alpha`, a sin `alpha`) and (a.cos `beta`, a sin `beta`)

Find distance PQ between the points P ( a cos alpha, a sin alpha) and Q ( a cos beta, a sin beta) .

The distance between the points ( a cos alpha, a sin alpha ) and ( a cos beta, a sin beta ) is

The distance between the points (a cos alpha,a sin alpha) and (a cos beta,a sin beta) where a> 0

The distance between the points (a cos alpha,a sin alpha) and (a cos beta,a sin beta) where a>0

The distance between the points (a cos alpha, a sin alpha) and (a cos beta, a sin beta) is a) 2|sin((alpha-beta)/(2))| b) 2|a sin((alpha-beta)/(2))| c) 2|a cos((alpha-beta)/(2))| d) |a cos((alpha-beta)/(2))|

Express the following in a+ib form: ((cos alpha+i sin alpha)^(4))/((sin beta+i cos beta)^(5))

Express the following in a + ib form: ((cos alpha + i sin alpha)^(4))/((sin beta + i cos beta)^(5))

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

(sinalpha cos beta+cos alpha sin beta)^2+(cos alpha cos beta-sin alpha sin beta)^2=1

If sin beta is the G.M between sin alpha and cos alpha then (cos alpha - sin alpha)^(2) - 2 cos^(2) beta =
