Question

Find the value of If x = a (sec teta + tan teta ) and y= b(sec teta - tan teta ), then x2 y2 =​

Answer 1

Step-by-step explanation:

We have x 2 - y 2 = [ 2 - 2 ]. = - ( a 2 tan 2 θ + b 2 sec 2 θ + 2 a b tan θ sec θ ). = a 2 sec 2 θ + b 2 tan 2 θ - a 2 tan 2 θ - b 2 sec 2 θ. = ( a 2 sec ...
