Cos 2x + 3sinx-2 = 0

(sinx - 1)(sinx - 2) = 0 sinx = 1 and sinx = 2 x = pi/2 and x = O/ Hence, the solution set is {pi/2}. Hopefully this helps! 3sin(2x)-2cos(x)=0 .

1 cos(x). 1. √32. √22 = 1 + 2 cos(x) − 7 cos(x) + 2 sin(x + π) + 3(−sin(x)) = −4 cos(x) − 2 sin(x) − 3 sin (x) Les solutions dans R de l'équation sin(x) = cos(2x) sont le а) Решите уравнение $cos (2x) + 3 sin x — 2 = 0$. б) Найдите корни уравнения, принадлежащие отрезку $[-3π;-π]$. Показать ответ.

Example 24 Solve 2 cos2 x + 3 sin x = 0 2 cos2x + 3 sin x = 0 2 (1 − sin2 x) + 3 sin x = 0 2 – 2 sin2x + 3 sin x = 0 –2sin2x + 3sin x + 2 = 0 Let sin x = a So, our equation becomes sin2 x + cos2 x = 1 cos2 x = 1 – sin2 x –2a2 + 3a + 2 = 0 0 = 2a2 – 3a – 2 2a2 – 3a – 2 = 0 2a2 – 4a + a – 2 = 0 2a (a – 2) + 1 (a – 2) = 0 (2a + 1) (a – 2) = 0 Hence 2a + 1 Solution for cosx+3sinx=2 equation: Simplifying cosx + 3sinx = 2 Solving cosx + 3insx = 2 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. A good starting point would be to expand the double angle formula: cos(2x) = 1 - 2(sin(x))^2 From here, the problem becomes almost like the high school quadratic equation types you see everywhere. 2(sin(x))^2 - 3sin(x) + 1 = 0 résoudre dans R cos2x-3sinx-2=0 : exercice de mathématiques de niveau première - Forum de mathématiques. 18 Apr 2016 S={π6+2πn,5π6+2πn,x=π2+2πn}.

Math. Multiply then use fundamental identities to simplify the expression below and determine which of the following is not equivalent (2 - 2cos x)(2 + 2cos x) a.4 - 4cos^2 x b . 4 - cos^2 x c.4/(1 + cot^2 x) d. 4sin^2 x e.4/(csc^2 x) The equation 3sinx+cos^2x=2 is solved below - 9996341 Exactly, sin^2(x)-3sin(x)+1 does not have a rational factor. So it was factored incorrectly.

Let s = sinx (just to simplify the notation), then 2 sin^2x - 3 sinx + 1 = 2s^2 - 3s + 1 = 0. To solve, just factor: (2s +- 1)(s + 1) = 0. The solutions are 2s + 1 = 0, s = -1/2 Simple and best practice solution for 2sinx=3cosx equation. Check how easy it is, and learn it for the future. Our solution is simple, and easy to understand, so don`t hesitate to use it as a solution of your homework.
