Find A values
csc (6a +π/8)=sec (2a -π/8).
cosec(6a+pi/8)=sec(2a-pi/8)
=>sin(6a+pi/8)=cos(2a-pi/8)
=>sin(6a+pi/8)=sin(pi/2-2a+pi/8)
=>6a+pi/8=5pi/8-2a
=>8a=4pi/8
=>a=pi/4=the principal value
it becomes lengthy for integral values.the answer is
a=1/3*n*pi+pi/16 where n belongs to integral values.please comment!!
