Respuesta :
To prove that the trignometric identity sinθ cot θ is equal to cos θ, you can use the following:
sinθ cotθ = cosθ sinθ(cosθ/sinθ) = cosθ
cancel sinθ on the numerator and denominator and you will get:
cosθ = cosθ
sinθ cotθ = cosθ sinθ(cosθ/sinθ) = cosθ
cancel sinθ on the numerator and denominator and you will get:
cosθ = cosθ
Answer:
Step-by-step explanation:
sinθcotθ=cosθ
sinθ[tex]\frac{cos}{sin}[/tex]θ=cosθ
cosθ=cosθ
