Let's plot the points representing the coordinates (1,3),(0,5), (2,1),(3,3),(1,3),(2, 5) and (0,0) on the graph paper.

Harmonic conjugate of the point (5, 13) with respect to (2,-5) and (3,1) is (1,(13)/5) (b) ((13)/5,1) ((13)/5,7/5) (d) (-7/5,(13)/5)

Harmonic conjugate of the point (5,13) with respect to (2,-5) and (3,1) is (1,(13)/(5))(b)((13)/(5),1)((13)/(5),(7)/(5)) (d) (-(7)/(5),(13)/(5))

(1)/(3)+(1)/(3.3^(3))+(1)/(5.3^(5))+(1)/(7.3^(7))+....=

Which among the following is true for the given numbers? (A) 13//33 (B) 13//33 (C) 13//33 (D) 20//47 < 13//33 < 32//47 <25//27

show that cos^(-1)""((4)/(5))+ cos^(-1) ((12)/(13)) =cos^(-1) ""((33)/(65))

Prove that : cos^-1(12/13) + sin^-1(3/5) = cos^-1(33/65)
