The domain and range of a relation are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively
Evaluate the following :
Problem 1 :
Solution :
For what angle measure of cosine, we get -1/2. Range of cos^{-1} function is [0, π]
Using ASTC formula, in 2nd quadrant and in 3rd quadrant, we have negative sign for cosine.
So, the required angle = π - (π/3)
= 2π/3
Problem 2 :
Solution :
For what angle measure of cosine, we get 1/2. Range of cos^{-1} function is [0, π]
