  7. LHS = (sin^2(x) + 2sinx + 1) / cos^2(x) Now, we know that a^2 + 2ab + b^2 = (a + b)^2 Using the above identity...the identity: a^2 - b^2 = (a - b)(a + b), here: a = 1 and b = sinx] Now substituting (i) and (ii) in LHS , we have: LHS = (sin^2(x) + 2sinx + 1) / cos^2(x) = (1 + sinx)^2 / [(1 - sinx)(1 + sinx)] = (1 + sinx...
