,
, and
We begin by rewriting the left side in terms of sin and cos, since all the identities deal with sines and cosines and no cotangents or cosecants. Rewriting gives you:
Notice I also wrote the 1 in terms of sin^2(x).
Now we will put the numerator of the bigger fraction over the common denominator:
The rule is bring up the lower fraction and flip it to multiply, so that will give us:
And canceling out the sin^2 x leaves us with just
which is one of our identities.
Question is Incomplete; Complete question is given below;
Mr. Lin hires a moving company to help transport furniture to his new home. The bill from the moving company is $400. Mr. Lin includes a 15% tip with his payment.
What is Mr. Lin’s total payment, including tip?
Answer:
Mr. Lin made a Total payment of $460 including the Tip.
Step-by-step explanation:
Given:
Total bill = $400
Percentile amount paid in tip = 15%
We need to find the total payment, including tip.
