Answer:
Step-by-step explanation:
Given function is,
f(x) =
Equation form of the function will be,
y =
Interchange x and y,
Solve for y,
y = 2x + 1
Therefore, inverse of the function 'f' will be,
Now = 2 - [2x + 1]
= -2x + 1
Value of = f(2x + 1)
From the given function,
f(2x + 1) =
= x
Therefore, value of
It cannot be simplified, it is already reduced its broken down into lowest terms .
Answer:
Ф lies in the 2nd quadrant
Step-by-step explanation:
1. If angle Ф lies in the 1st quadrant, then
- sin Ф is a positive value
- cos Ф is a positive value
- tan Ф is a positive value
2. If angle Ф lies in the 2nd quadrant, then
- sin Ф is a positive value
- cos Ф is a negative value
- tan Ф is a negative value
3.If angle Ф lies in the 3rd quadrant, then
- sin Ф is a negative value
- cos Ф is a negative value
- tan Ф is a positive value
4. If angle Ф lies in the 4th quadrant, then
- sin Ф is a negative value
- cos Ф is a positive value
- tan Ф is a negative value
∵ sec Ф < 0
∴ sec Ф is a negative value
∵ cos Ф = 1/sec Ф
∴ cos Ф is a negative value
∵ csc Ф > 0
∴ csc Ф is a positive value
∵ sin Ф = 1/csc Ф
∴ sin Ф is a positive value
→ By using the second rule above
∴ Ф lies in the 2nd quadrant
