Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries. Solved: Solve: 2cos^2(x) + 3cos(x) = 0. By signing up, you'll get thousands of step-by-step solutions to your homework questions. You can also ask And then, the first of these formulae becomes: Cos(t + t) = Cos t cos t – Sin t sin t. so that Cos 2t = Cos 2 t – Sin 2 t. And this is how we get second double-angle formula, which is so called because you are doubling the angle (as in 2A).

{pi/2} Factor to solve. (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!

Solve: 2 cos^2x - 3 cosx + 1 = 0 for 0 Pre-Calculus If sinA=3/5 when pi/2 A pi and cosB=5/13 when 3pi/2 B 2pi, find the exact value of the function cos(5pi/6+B). решение уравнения Cos^2x+3sinx-3=0 Homyash18 Знаток (490), закрыт 8 лет назад 1-sin^2x+3sinx-3=0 Замена t=sinx приводит к обычному квадратному уравненю: -t^2+3t-2=0 или t^2-3t+2=0, находим корни t1=2, t2=1. Имеем: May 10, 2009 · use the identity that cos 2x = 1 - 2 sin^2 x (1 - 2sin^2 x) + 3 sin x - 2 = 0-2 sin^2 x + 3sin x - 1 = 0. 2sin^2 x - 3 sin x + 1 = 0 (2 sin x - 1)(sin x - 1) = 0. so either 2sin x - 1 = 0 ==> sin x = 1/2 ==> x = pi/6 + 2pi*n or. x = 5pi/6 + 2pi*n (n is an integer) or sin x - 1 = 0 ==> sin x = 1 ==> x = pi/2 + 2pi*n.
