If cosec theta = 3/2, then find the value of 2 ( cosec2 theta + cot2 theta )

Mathematics
1 answer:
NISA [10]3 years ago
8 0

Answer:

7

Step-by-step explanation:

Using the trigonometric identity

• 1 + cot²x = cosec²x, then

2(cosec²Θ + cosec²Θ - 1 )

= 2(2cosec²Θ - 1)

= 4cosec²Θ - 2

= 4 × (\frac{3}{2} )² - 2

= 4 × \frac{9}{4} - 2

= 9 - 2

= 7

Which best represents the equation of this circle ?
likoan [24]

The equation of a circle:

(x-h)^2+(y-k)^2=r^2

(h, k) - center

r - radius

Look at the picture:

center: (4, -2) → h = 4, k = -2

radius: r= 5

Substitute:

(x-4)^2+(y-(-2))^2=5^2\\\\(x-4)^2+(y+2)^2=25\to\boxed{B.}
