Answer 1

I know the answers are 7pi/6 and 11pi/6, but I don't know the general formula

Answer 2

@ksaimouli

Answer 3

is it x=pi/6 +kpi

Answer 4

@ikram002p is this correct?

Answer 5

limme check

Answer 6

2sin^2 x-5sinx-3=0
(2sin x +1) (sin x-3)=0
2 sin x +1 = 0
sin x =1/2
x= sin^-1 1/2=pi/6 + kpi ur correct

Answer 7

so that is the general formula!!??

Answer 8

pi/6 + k2pi
