Web19 apr. 2016 · The general solution of the equation sin2θ sec θ + √3 tan θ = 0 is: Q9. The values of x satisfying 2 sin 2 x − 2 cos 2 x = 1 are: Q10. Each side of a square ABCD … Web1 okt. 2024 · If tanA + cotA = 2, then tanA + 1/tanA =2. This equation is of the x +1/x = 2. Now for all values of x, x + 1/x is always greater than equal to 2. It is equal to 2 when x =1. Hence tan A = 1, implying A =45 degrees. Thus tan^2 A - cot^2 A is actually 0, since both tan 45 and cot 45 =1 Answered by: Aritra D. from Kolkata Like Answer: dragon\u0027s breath bm
