Solving Sin2x Cosx Math Trigonometry Equations And Inequalities The solutions are s={1 2pi, 3 2pi, 1 6pi, 5 6pi} we need sin2x=2sinxcosx therefore, sin2x=cosx sin2x cosx=0 2sinxcosx cosx=0 cosx(2sinx 1)=0 so, {(cosx=0),(2sinx 1=0. Solve problems from pre algebra to calculus step by step step by step. sin2x=cosx. en. related symbolab blog posts. practice makes perfect.
Solve Sin 2x Cos X 0 Youtube First observe that cosu = cosv when u v = 2nπ or u − v = 2nπ for any integer n. we then have sin(2x) = cos(π 2 − 2x). so: cos(π 2 − 2x) = cos(x). then we have the two possibilities defined above. possibility 1: so x = π 2 plus multiples of 2π. possibility 2: so x = − π 2, π 6 or 5π 6 plus multiples of 2π.
