Simplify: cot(θ)sin(θ)

cos(θ)

Step-by-step explanation:

cot(θ) = cos(θ)/sin(θ)

Step 1: Write expression

cot(θ)sin(θ)

Step 2: Substitute

cos(θ)/sin(θ) · sin(θ)

Step 3: Simplify

cos(θ)

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
