Trig
graphs are periodic repeating cycles) so multiple solutions are
possible. What would the next solutions above 360° be? Mouseover "solutions" to see the graph change 


x = Sin^{1}(0.7)  
180  x =  
Find the first solution by the same method. The Cos graph shape means we take the first solution off 360 for the 2nd solution.
What would the next solutions above 360° be? Mouseover "solutions" to see the graph change 


x = Cos^{1}(0.3)  
360  x =
