  2. Which of the following equations describe the condition for observing the fourth dark fringe in an interference pattern
  3. At which of the following values is sin θ negative?(1 point)Responses sinθ=120° sinθ=0° sinθ=270° sinθ=90°
  4. Which of the following equations describes the condition for observing the fourth bright fringe in Young's double-slit
  5. At which of the following values is sin θ negative?(1 point)sinθ=120° sinθ=270° sinθ=0° sinθ=90°
  6. Hi. I am reposting this. Can you verify. Thanks.(cosθ) / (sinθ – 1) + (cosθ)/ (1 + sinθ) = -2tanθ (1 / cos^2θ) – (2)
  7. 1. (P -15/17, -8/17) is found on the unit circle. Find sinΘ and cosΘWork: P= (-15/17, -8/17) cosΘ = a value P = (a,b) sinΘ =
  8. Which of the following equations represents sinθfor a point (x,y) on the unit circle?(1 point) Responses sinθ=y sine theta
  9. Which of the following equations represents sinθfor a point (x,y) on the unit circle?(1 point) Responses sinθ=y sine theta
  10. Find f.f ''(θ) = sin θ + cos θ, f(0) = 5, f '(0) = 3 My steps: f'(θ)=cosθ-sinθ+C When f'(0)=3, C=-2, so
