Approximate to the nearest 10' the solutions of the equation in the interval (o, 360).
sin^2(t)-8 sin(t)+3 = 0
-------
Use the Quadratic Formula to get::
sin(t) = [8 +- sqrt(64-4*1*3)]/2 = [8+- sqrt(52)]/2
sin(t) = 7.606.. (extraneous)
sin(t) = 0.3944
---
Ans::: t = arcsin(0.3944) = 23.23 degrees = 23 deg 14 minutes
