Question 849365: How do you Verify the identities: (sin(x))(cos(y))+(cos(x))(sin(y))/(cos(x))(cos(y))-(sin(x))(sin(y))= tan(x)+tan(y)/1-(tan(x))(tan(y)) Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! How do you Verify the identities: (sin(x))(cos(y))+(cos(x))(sin(y))/(cos(x))(cos(y))-(sin(x))(sin(y))= tan(x)+tan(y)/1-(tan(x))(tan(y))
-----
sin(x+y)/cos(x+y) = tan(x+y)
