solve 3sin(2t+1) = -0.8142 from 0<t<2pi
please show working as I need to know how these answers where found
1.21 2.51 4.35 5.65
I dont really understand what 3sin(2t+1) means
The range required is
2t+1=3.416 , 6.008 , 6.558 , 9.15 (all in radians)
Since sin is negative here , so t would be in the 3rd and fourth quadrant . I am sure you know this .
THen now , just do the algebra or in other words solve for t and you would get the answers .
