1. 1
2. 1
3. 1
4. 1
5. For theta zero , all values are 1

Answer 2

Answer:

1. 1

2. 1

3. 1

4. 1

Step-by-step explanation:

Let theta be x

√2 sin(π/4 + x)

√2 [sin(π/4)cosx + cos(π/4)sinx]

√2 [(1/√2)cosx + (1/√2)sinx]

cosx + sinx = cos(theta) + sin(theta)

If theta = 0, sin(theta) = 0, cos(theta)=1

1. 1 - 0 = 1

2. 1 + 0 = 1

3. 1 + 0 = 1 [ tan(theta)=0 if theta = 0 ]

4. 1 + 0 = 1
