WebInverse cosine is the inverse of the basic cosine function. In the cosine function, the value of angle θ is taken to give the ratio adjacent/hypotenuse. However, the inverse cosine function takes the ratio adjacent/hypotenuse and gives angle θ . cos -1 (adjacent/hypotenuse) = θ Inverse cosine symbol WebAs the other answer says, you simply can't express all values of trigonometric functions as fractions. I am guessing that on your TI-84, if you set the calculator to give you the fractions, then sin ( 30 ∘) = sin ( π / 6) will give you 1 2 (that is how it works on my TI-84).
