How many possible values for y are there where y= Cos -1 0
A.) 0
B.) 1
C.) infinite
D.) 2
Answer:
B) 1 possible value
FOR THIS SPECIFIC INSTANCE
Step-by-step explanation:
If it is Cos -1 (0) and cos is capitalized, that means it is a function and you apply restrictions. Based on the restrictions you get one possible value (I think the value is pi/2)
However, if the problem is cos -1(0) with no capitalization, it is a relation meaning values are infinite because of repetitions. The answers would be pi/2 and 3pi/2 and both would be added/subtracted by 2n(pi).
Answer:
B
Step-by-step explanation:
