Best ResponseYou've already chosen the best response.1left side becomes: \[\sec A + {\left( {\csc A} \right)^2} = \frac{1}{{\cos A}} + {\left( {\frac{1}{{\sin A}}} \right)^2} = ...\] please continue

Best ResponseYou've already chosen the best response.1ok! so left side becomes: \[{\left( {\sec A} \right)^2} + {\left( {\csc A} \right)^2} = {\left( {\frac{1}{{\cos A}}} \right)^2} + {\left( {\frac{1}{{\sin A}}} \right)^2} = ...\]

Best ResponseYou've already chosen the best response.0ok m calling sinA = x nd cosA=y 1/y^2 +1/x^2 take LCM we get  (x^2 + y^2)/(xy)^2 we know that sin^2A+cos^2A = 1 therefore the numerator = 1 nd we r left with 1/(xy)^2 =sec^A cosec^A
