ok since nobody asked an questions im gonna just give two examples...

Example #1: Find the angle of inclination...

2x+5y=15

m=-2/5

tan=-2/5

alpha=tan^-1(-2/5)

Example #2: For a triangle with C=36 degrees a=5 b=6, find side c....

c^2=5^2+6^2-2(5)(6)

cos36c=sqrt(25+36-2(5)(6)cos36)

c= 3.53

i hope this might help someone...& Happy Thanksgiving Everyone!!!
