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.
r=sqrt x^2+y^2
r=sqrt 5^2+4^2
r=sqrt 41
sin=y/r
sin=4/sqrt 41
cos=x/r
cos=5/sqrt 41
tan=y/x
tan=4/5
csc=r/y
csc=sqrt 41/4
sec=r/x
sec=sqrt 41/5
cot=x/y
cot=5/4

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)
