WebIf we consider the right angle, the side opposite is also the hypotenuse. So sin (90)=h/h=1. By pythagorean theorem, we get that sin^2 (90)+cos^2 (90)=1. So, substituting, 1+cos^2 (90)=1 cos^2 (90)=0 cos (90)=0 And we see that tan (90)=sin (90)/cos (90)=1/0. So tan (90) is undefined. ( 7 votes) Show more...
