If
2 sin theta - cos theta/ cos theta + sin theta = 1, then value of cot theta is
Answers
Answer:
cotθ=1/2
Explanation:
2 sinθ-cosθ/cosθ+sinθ=1
2 sinθ-cosθ=cosθ+sinθ
sinθ=2cosθ
cotθ=cosθ/sinθ
cosθ/sinθ=1/2
cotθ=1/2
Answer:
Value of cotθ =
Explanation:
- Formulation of cotθ: We know, for a right angle triangle
sinθ = height/hypotenuse. ⇒ height = sinθ*hypotenuse
cosθ = base/hypotenuse. ⇒ base = cosθ*hypotenuse
cotθ = base/height
= cosθ*hypotenuse/sinθ*hypotenuse
=cosθ/sinθ
- Calculation of cotθ: Given (2sinθ - cosθ)/(cosθ + sinθ) = 1
⇒ 2sinθ - cosθ = 1 * (cosθ + sinθ)
⇒ 2sinθ - cosθ = cosθ + sinθ
⇒ 2sinθ - sinθ = cosθ + cosθ
⇒ sinθ = 2cosθ
⇒ 2cosθ/sinθ = 1
⇒ 2cotθ = 1
⇒ cotθ = 1/2
