[DOC File]7-3 The Sine and Cosine Functions
https://info.5y1.org/trig-solution-set-calculator_1_ef85e7.html
Solution: Since the angle is in the second quadrant, x must be negative implying Cos must also be negative. ... Since the trig functions are all periodic graphs, none of them pass the horizontal line test. ... Set calculator mode to rads. 1) Cos-1 (-.5) = 2.09 rounded to nearest hundredth. 2) Sin-1(-.75) = -.85.
[DOC File]Using Inverse Trig Functions outside 00 to 900
https://info.5y1.org/trig-solution-set-calculator_1_bbd519.html
On the graph, there is one solution between -900 and 00, another solution between 900 and 1800, and a third solution between 2700 and 3600. A calculator gives. That solution is not in our interval, but we can use that to find the two solutions in the interval: and . Thus, the solution set for where is. Example 4: Find all solutions to where .
