WebbCalculating the area of a triangle is an elementary problem encountered often in many different situations. The best known and simplest formula is = /, where b is the length of the base of the triangle, and h is the height or altitude of the triangle. The term "base" denotes any side, and "height" denotes the length of a perpendicular from the vertex opposite the … WebbAs we know, sin 2 x = 2 · sin x · cos x. ∴ sin 2 x = 2 · sin x · cos x × cos x cos x = 2 · sin x cos x · cos 2 x = 2 · tan x · 1 sec 2 x [ ∵ sin x cos x = tan x and cos x = 1 sec x] = 2 tan x 1 + …
