Factor the left side of the equation. Tap for more steps. Substitute for all occurrences of.
Tap for more steps. For a polynomial of the form , rewrite the middle term as a sum of two terms whose product is and whose sum is. In our problem 0° ≤ x ≤ 540°.
So number of values are 4 like 30°, 150°, 390°, 510°. Jadi himpunan penyelesaiannya adalah { 1 / 12 π, 5 / 12 π, 13 / 12 π, 17 / 12 π} F (x) = 2sin2x −5sinx −3 = 0.
Solve this quadratic equation for sin x. There are 2 real roots: Sinx = − 2 4 = − 1 2, and sin x = 3 (rejected as > 1) sinx =.
If any individual factor on the left side of the equation is equal to 0 0, the entire expression will be equal to 0 0. Sin(x)+1 = 0 sin ( x) + 1 = 0. 2sin(x)+ 3 = 0 2 sin ( x) + 3 = 0.
Set the first factor equal to 0 0 and solve. Tap for more steps. Set the first factor equal to 0 0.
Tap for more steps. If any individual factor on the left side of the equation is equal to 0 0, the entire expression will be equal to 0 0. Soal di atas bisa kita selesaikan dengan melakukan perhitungan seperti berikut:
Misalkan sin x = p, sehingga: Jadi h impunan penyelesaiannya adalah {30°, 150°}. Lý thị nga hỏi từ app vietjack.
