Answers

Answered by AmandeepMohanty

2

Step-by-step explanation:

sinØ-cos∅ = 0

squaring both side

(sinØ-cos∅)² = 0

sin²∅+cos²∅-2sinØcosØ = 0

1 -2sinØcosØ = 0

2sinØcosØ = 1

evaluating (sinØ+cosØ)²

(sinØ+cosØ)² = sin²∅+cos²∅+2sinØcosØ (sinØ+cosØ)² = 1+1 (2sinØcosØ = 1)

(sinØ+cosØ)² = 2

sinØ+cosØ = ±√2
