1. ( = arcsin(h/10) (Note: This could also be done using arctangent or arccosine functions. The inverse sine function is the easiest to work with in this example. Why?) 2. ( = arctan(8/h) (Note: This could also be done using arcsine or arccosine functions. The inverse tangent function is the easiest to work with in this example. Why?) 3. ................
