Find an expression equivalent to 1-sinx ^2/1-cosx ^2

madam [21]

Answer:

cot²x

Step-by-step explanation:

Using the identity

sin²x + cos²x = 1, then

1 - sin²x = cos²x

1 - cos²x = sin²x

Thus

$\frac{1-sin^2x}{1-cos^2x}$ = $\frac{cos^2x}{sin^2x}$ = cot²x

The value of 9−y is twice the value of y. What is the value of y?

ElenaW [278]

Answer:

y = 3

Step-by-step explanation:

9 - y = 2y

<u>Step 1: Add y to both sides</u>

9 - y + y = 2y + y

9 = 3y

<u>Step 2: Divide both sides by 3</u>

9 / 3 = 3y / 3

3 = y

Answer: y = 3
