7 / cot ^2A - 7 / cos ^2A
= 7 tan^2 A - 7 / cos ^2 A
= 7sin^2 A / cos^2 A - 7 / cos ^2 A
= 7 sin^2 A - 7 / cos ^2 A
= 7 ( sin^2 A - 1 ) / cos^2 A
= 7 cos^2 A / cos^2 A
= 7
so your required answer is 7
= 7 tan^2 A - 7 / cos ^2 A
= 7sin^2 A / cos^2 A - 7 / cos ^2 A
= 7 sin^2 A - 7 / cos ^2 A
= 7 ( sin^2 A - 1 ) / cos^2 A
= 7 cos^2 A / cos^2 A
= 7
so your required answer is 7
