WebFeb 1, 2024 · Now, we recall the cofunction identities from the previous section and use them to transform \cos (45\degree) cos(45°) into a sine: \cos (45\degree) = \sin (90\degree - 45\degree) = \sin (45\degree) cos(45°) = sin(90° − 45°) = sin(45°) This way, we can use the sine formula to find the answer. 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... Brendon Josh Orate 5 years ago WebFor cos 300 degrees, the angle 300° lies between 270° and 360° (Fourth Quadrant ). Since cosine function is positive in the fourth quadrant, thus cos 300° value = 1/2 or 0.5 Since the cosine function is a periodic function, we can represent cos 300° as, cos 300 degrees = cos (300° + n × 360°), n ∈ Z. ⇒ cos 300° = cos 660° = cos 1020°, and so on. shows from the 70s
