Find the exact values of the six trigonometric functions 0 if the terminal side of 0 in standard position contains the points(-5,-4).
(0 is not the number zero I don't know what its called)
I have to find r first.
they are all correct
but I would write tanß = 4/5
also you have no angle after your trig names
to say sin = 4/5 is a sin. (math joke)
