If cosθ + sinθ = \(\sqrt {2 }\)sinθ; then find value of cotθ
Answer & explanation
Correct answer: option 2
cosθ + sinθ = \(\sqrt {2 }\)sinθ
⇒ cotθ + 1 = \(\sqrt {2 }\) (divide by sinθ)
⇒ cotθ = \(\sqrt {2 }\) - 1
If cosθ + sinθ = \(\sqrt {2 }\)sinθ; then find value of cotθ
Correct answer: option 2
cosθ + sinθ = \(\sqrt {2 }\)sinθ
⇒ cotθ + 1 = \(\sqrt {2 }\) (divide by sinθ)
⇒ cotθ = \(\sqrt {2 }\) - 1
