India ranked 132nd among 191 countries and territories on the 2021 Human Development Index (HDI). In the 2020 report, India had ranked 131st among 189 countries and territories. The decline in the country’s performance from its previous level was on account of a fall in life expectancy.
If A, B and C are angles of triangle, then sin2A + sin2B + sin2C– 2cosA cosB cosC
In triangle ABC, ∠A - ∠B = 16 ° , whereas ∠A - ∠C = 8 ° , find ∠B.
Determined the simplified value of the given expression:(1 - sin2 q) X (sec q + tan q) X (sec q - tan q) X cosec2 q
If tan 4θ = cot 14θ, then find the value of cos 9θ.
The Value of (sin38˚)/(cos52˚) + (cos12˚)/(sin78˚) - 4cos²60˚ is
If sin 2A = cos (3A - 60o) , then find the value of sec 2A.
If cot8A = tan(A+8˚), find the value of A? Given that 8A and A+8 are acute angles.
