Which Pythagorean identity is correct?
sine squared (theta) + 1 = cosecant squared (theta)
tangent squared (theta) + 1 = secant squared (theta)
1 minus cotangent squared (theta) = cosecant squared (theta)
1 minus cosine squared (theta) = tangent squared (theta)

Option 2:

tangent squared (theta) + 1 = secant squared (theta)

Step-by-step explanation:

1 + tan²X

1 + sin²X/cos²X

(cos²X + sin²X)/cos²X

1/cos²X

sec²X

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
