Question 1183232
solve sin(x)=-0.86 on 0≤x<2pi
There are two solutions, A and B, with A < B and A and B in radians to 4 decimal places 
A=
B= 

how do I do this problem ?
~~~~~~~~~~~~~~~~~ 


<pre>
The given equation

    sin(x) = -0.86

has two solutions in the given interval 0 <= x < 2pi.



One solution is in the third quadrant, QIII,

    x = arcsin(0.86) + {{{pi}}} radians = 1.03527 + 3.14159 radians = 4.1769 radians.



Second solution is in the fourth quadrant, QIV,

    x = {{{2pi}}} - arcsin(0.86) radians = 2*3.14159 - 1.03527 radians = 5.2479 radians.



<U>ANSWER</U>.  The two solutions in the given interval are  A = 4.1769 radians  and  B = 5.2479 radians  (rounded as requested).
