Evaluate `sin2A, cos2A` and `tan2A` if:
i) `sinA=5/13`, ii) `cosA=8/17`, iii) `tanA=4/3`

If cosA=24/25 , evaluate the following, given that 0 lt A lt pi/2 . i) sin2A ii) cos 2A iii) tan 2A

If cosA=24/25 , evaluate the following, given that 0 lt A lt pi/2 . i) sin2A ii) cos 2A iii) tan 2A

If sinA, cosA and tanA are in G.P., then cos^(3)A+cos^(2)A=?

If tanA=-3/4 and pi/2 lt A lt pi , find the values of the following: i) sin(A/2) ii) cos(A/2) , iii) tan(A/2)

If sinA = -5/13 and pi lt A lt (3pi)/(2) , find the values of the following: i) sin(A/2) , ii) cos(A/2) , iii) tan(A/2)

If cosA=-3/5 and pi/2 lt A lt pi , find the values of the following: i) sin2A , ii) cos2A , iii) tan2A
