Question

If sinθ−cosθ=0, then Find the value of (sinθ+cosθ).

Answer 1

Answer:

2cos Ф

Step-by-step explanation:

sinФ-cosФ=0

sinФ=cosФ

so, sinФ+cosФ=cosФ+cosФ=2cosФ

Answer 2

Answer:

sin theta- cos theta=0

sin theta = cos theta

sin 45°=cos45⁰

1/√2=1/√2

sin theta + cos theta

1/√2 + 1/√2

2/√2 × √2/√2

2√2 /2

√2
