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...

WebJan 29, 2024 · In the case of the tangent function, tan ( θ) is simply the slope of the terminal side of θ, when the angle is in standard position. Slopes can be negative, therefore tangent values can be negative. As for cosines, if you believe the double-angle formula for cosine, apply it to a 60 ∘ angle, and see what happens! WebHere is the question. Sketch a angle theta in standard position such that theta has the least possible positive measure, and the given point is on the terminal side of theta.
