Find all real numbers in the interval [0,2pi) that satisfy the equation. 3sec^2 x tan x =4tan x 3. Simplify the following trigonometric expressions, using identities as needed: A -5 dan -2 B. -5 dan 2 C. -2 dan 5 D. 5 dan -2 E. 5 dan 2 . Jawaban: D Pembahasan: dari persamaan matriks di atas, kita peroleh. 3a - 10 = 5 3a = 5 + 10 3a = 15 a = 15/3 a = 5. dan-6 - 5b = 4-5b = 4 + 6-5b = 10 b = 10/(-5) b = -2. Jadi, nilai a dan b berturut-turut adalah 5 dan -2.
