Answer:
pi/2
Step-by-step explanation:
Arccos(tan(0))
Arccos( 0) since tan(0)=0
Arccos(0)=pi/2 since cos(pi/2)=0 and the restricted domain of cosine is [0,pi].
Answer:
1
Step-by-step explanation:
First of all go one step at a time. Find tan(0). For this question, you can use your calculator.
Tan(0) = 0 That's because the opposite side has a length of 0 and the tangent's definition is
Tan(x ) = opposite side / adjacent side. The opposite side and the adjacent side are part of the same length. There is no real opposite side.
=========
Now you are down to cos-1(0)
If you put that into your calculator like this
2nd Function
cos-1(
0
)
=
You will get 1
