For the equation
sin(8 x) = 0.91
find the smallest solution, the largest solution and the number of solutions for x in the interval 0 ≤ x ≤ 2π.
The first two answers should be given accurate to two decimal places.
------------
8x = arcsin(0.91) = 1.143 radians or l8x = (pi)-1.143 = 1.9983 radians
------
smallest solution:: 1.143/8 = 0.1429
largest solution:: 1.9983/8 = 0.2498
