Question

What is the cosine rational form of 60 degrees?

Answer 1

cos(60deg)= 1/2

Answer 2

This would be a 30-60-90 triangle, so the smaller side is half the length of the hypotenuse, so 1/2

Answer 3

Cos60 = 1/2

Answer 4

The cosine ratio in rational form for a 60° angle is?
How exactly do I do this? I understand the first example,

Answer 5

Well, 60 degrees in the radian form is pi/3 why? pi=180 and 180/3 gives you 60
So, cos60 =cos pi/3 = 1/2 by rule.

Answer 6

So would the tan90 also be 1/2?
