sin(-\theta )\implies -sin(\theta )\qquad \qquad cos(-\theta )\implies cos(\theta )
\\\\\\also~recall\\\\ sin^2(\theta)+cos^2(\theta)=1\implies cos^2(\theta)=1-sin^2(\theta)

[1-cos(-t)][1+cos(t)]\implies [1-cos(t)][1+cos(t)]

\bf 1^2-cos^2(t)\implies 1-cos^2(t)\implies sin^2(t)\\\\

%Simplify each expression.  (1−cos⁡(−t))(1+cos⁡(t)) =  (1+sin(t))(1+sin(-t))=  csc⁡(t)tan⁡(t)+sec⁡(−t) =
[1+sin(t)][1+sin(-t)]\implies [1+sin(t)][1-sin(t)]
\\\\\\

Which is bigger, a third of 45 or one-sixth c<br> 138?
Ksju [112]

Applying the knowledge of fractions, the bigger one is: one-sixth of 138.

<h3>What are Fractions?</h3>

Fractions can be defined as a part of a digit or number, and are not whole numbers. For example, a third is 1/3, one-sixth is 1/6, which are both fractions.

Therefore, let's evaluate each statement:

1/3 of 45 = 1/3 × 45 = 15

1/6 of 138 = 1/6 × 138 = 23

Therefore, the bigger of the two is: one-sixth of 138.

Leah and Carl share a 12-ounce box of cereal. By the end of the week, Leah has eaten
Anton [14]

Answer: Use Fractions and Multiplication.

Step-by-step explanation:

To start, you need to find 1/6 of 12. The easiest way to do this is to multiply 12/1 by 1/6. The answer is 12/6, which simplifies to 2. Then, you do the same for 2/3: 12/1*2/3=24/3, which simplifies to 8. You then add the results to figure out how much has been eaten. 8+2=10
