Question

If A+ B = 90° , find
cos B cos A tangent A cosec A/cosec B sin square B cot B + tan B/ cot A​

Answer 1

Answer: HEY MATE ✌HOPE THIS HELPS

Step-by-step explanation:Given, LHS = root tan a tan b + tan a cot b/sin a sec b - sin^2 b/cos^2 a

      = root tan a tan(90-a) + tan a cot(90-a)/sin a sec(90-a) - sin^2(90-a)/cos^2 a

      = root tan a.cot a + tan a.tana/sin a.cosec a - cos^2 a/cos^2 a

      = root 1+tan^2 a/1 - 1

     = root tan^2 a

    = tan a.
