You can put this solution on YOUR website! Find all real solutions to four decimal places. 3 sin x+2=0
a. x= -.7297+2piek, k any integer b. x= -.7297+piek, k any integer
c. x=-.7297+piek, x=3.8713 + pie k, k any integer
d. -.7297 + 2pie k, x=3.8713+2piek, k any integer
***
3sinx+2=0
sinx=-2/3
x=3.8713+2πk, 5.5534+2πk, k=any integer (in quadrants III and IV in which sin<0)
or
x=-.7297+2πk, 3.8713+2πk, k=any integer (in quadrants III and IV in which sin<0)(ans d.)
