25 июня 2019 г., 07:01. Решить уравнение 2–cos2x+3sinx=0.

So it was factored incorrectly. 2cos^2x=3sinx 2(1-sin^2x)=3sinx 2-2sin^2x=3sinx 2sin^2x+3sinx-2=0 (2sinx-1)(sinx+2)=0 sinx=1/2 or sinx=-2 Sinx cannot equal -2 so, sinx=1/2 x=[30 +-n(360)]degrees and x=[(150)+-n(360)degrees] These are all the solutions.
