for 10. a
for 11. f.
Step-by-step explanation:
Given:
The terminal point of is (1,0).
To find:
The value of .
Solution:
If the terminal point of is (x,y), then
It is given that the terminal point of is (1,0).
Here, x-coordinate is 1 and the y-coordinate is 0. Using the above formula, we get
Therefore, the value of is 0.
