Answer: cotθ

Step-by-step explanation:

tanθ * cos²θ * csc²θ

=
(sin\theta)/(cos\theta) * \frac{cos\theta*cos\theta}{} *(1)/(sin\theta*sin\theta)

=
(cos\theta)/(sin\theta)

= cotθ

Answer: B

Step-by-step explanation:

The parent graph is y = x²

The new graph y = -x² + 3 should have the following:

  • reflection over the x-axis
  • vertical shift up 3 units

Answers:

  • a. Quadrant II
  • b. negative
  • c.
    (\pi)/(6)
  • d. C
  • e.
    -(√(3))/(3)

Step-by-step explanation:


(17\pi)/(6) - (12\pi)/(6) = (5\pi)/(6)

a) Quadrant 2 is:
(\pi)/(2) < \theta < \pi

b) In Quadrant 2, cos is negative and sin is positive, so tan is negative

c)
\pi-(5\pi)/(6) =
(\pi)/(6)

d) the reference line is above the x-axis so it is negative -->
-tan(\pi)/(6)

e)
tan((5\pi)/(6))=(1)/(-√(3))=-(√(3))/(3)
