Some companies do not accept referrals, as they believe in an unbiased hiring system, so check with your boss or HR to find out if yours does. Also, a position must be open in your company for you to refer someone for a position. You need to ask around and check any job listings to see if a position is open that your friend would fit. For example, you could ask friends in different departments if they've heard of any openings. Think about the openings that would be the best fit for your friend's skill set. If you're on friendly terms, you can also ask your boss if any openings are likely to come available soon. Make sure to let them know you're asking about jobs so you can refer a friend. If they're hiring in your department, then you'll need to send it to your boss. However, if it's another department, you may need to figure out who's on the hiring committee or send it to human resources. Sending an email is better than casually recommending a friend in person. It gives you a chance to play up their good qualities, plus the hiring committee has something to refer back to later. While you may want to start with some niceties, such as "How are you?" make sure you get to the point quickly. Bring up the position to get the conversation going, for instance. You could say, "I heard you were hiring for a new position, and I believe you're on the hiring committee." Next, you need to talk about why you're mentioning the position. They may think you are wanting to recommend yourself, so you need to be clear about what you want, making a recommendation for a friend. You could write, "If you're accepting referrals, I'd like to put in a good word for a friend of mine, Rachel Amador. She should be sending in an application in the next week." You also want to say why you think your friend will be a good fit for the position, not just bring up that they want the job. That way, you can help the person doing the hiring understand how your friend is a good fit. For instance, you could write, "Rachel is a hard worker, which I know because I worked with her at a previous job for 5 years. She always shows up on time and gets work down ahead of deadlines. She also has the initiative to see what needs to be done and do it." One thing you should do as you close the email is note that you welcome any questions that the hiring committee has about the person. You want to be available to allay any concerns they have about hiring your friend. For example, you could write, "I feel Rachel is a strong candidate for this position, so if you have any questions, feel free to approach me with them."

Trigonometry functions can be used to model real world situations involving lengths and angles. The first step is to define the situation with a right triangle model. For example, suppose you have the following problem: You are climbing a hill. You know that the peak of the hill is 500 meters above the base, and you know that the angle of the climb is 15 degrees. How far must you walk to reach the top? Sketch a right triangle and label the parts. The vertical leg is the height of the hill. The top of that leg represents the peak of the hill. The angled side of the triangle, the hypotenuse, is the climbing trail. When you have your sketch and have labeled the parts of it, you need to assign the values that you know. On the problem of the hill, you are told that the vertical height is 500 meters. Mark the vertical leg of the triangle 500 m. You are told that the climbing angle is 15 degrees. This is the angle between the base (bottom leg) of the triangle and the hypotenuse. You are asked to find the distance of the climb, which is the length of the hypotenuse of the triangle. Mark this unknown as x{\displaystyle x}. Review the information that you know and what you are trying to learn, and choose the trigonometry function that links those together. For example, the sine function links an angle, its opposite side and the hypotenuse. The cosine function links an angle, its adjacent side and the hypotenuse. The tangent function links the two legs without the hypotenuse. In the problem with the hill climb, you should recognize that you know the base angle and the vertical height of the triangle, so this should let you know that you will be using the sine function. Set up the problem as follows: sin=oppositehypotenuse{\displaystyle \sin heta ={
rac { ext{opposite}}{ ext{hypotenuse}}}} sin15=500hypotenuse{\displaystyle \sin 15={
rac {500}{ ext{hypotenuse}}}} Use basic algebraic manipulation to rearrange the equation to solve for the unknown value. You will then use either a table of trigonometric values or a calculator to find the value of the sine of the angle that you know. To find the length of the hill climb, solve the equation for the length of the hypotenuse. sin15=500hypotenuse{\displaystyle \sin 15={
rac {500}{ ext{hypotenuse}}}} hypotenuse=500sin15{\displaystyle { ext{hypotenuse}}={
rac {500}{\sin 15}}} hypotenuse=5000.259{\displaystyle { ext{hypotenuse}}={
rac {500}{0.259}}} hypotenuse=1930{\displaystyle { ext{hypotenuse}}=1930} With any word problem, getting a numerical answer is not the end of the solution. You need to report your answer in terms that make sense for the problem, using the proper units. For the hill problem, the solution of 1930 means that the length of the climb is 1930 meters. Consider one more problem, set up a diagram, and then solve for the unknown length. Read the problem. Suppose a coal bed under your property is at a 12 degree angle and comes to the surface 6 kilometers away. How deep do you have to dig straight down to reach the coal under your property? Set up a diagram. This problem actually sets up an inverted right triangle. The horizontal base represents the ground level. The vertical leg represents the depth under your property, and the hypotenuse is the 12 degree angle that slopes down to the coal bed. Label the known and unknown values. You know that the horizontal leg is 6 kilometers (3.7mi), and the angle measurement is 12 degrees. You want to solve the length of the vertical leg. Set up a trigonometry equation. In this case, the unknown value that you want to solve is the vertical leg, and you know the horizontal leg. The trigonometry function that uses the two legs is the tangent. tan=oppositeadjacent{\displaystyle an heta ={
rac { ext{opposite}}{ ext{adjacent}}}} tan12=opposite6{\displaystyle an 12={
rac { ext{opposite}}{6}}} Solve for the unknown value. opposite=tan126{\displaystyle { ext{opposite}}= an 12*6} opposite=0.2136{\displaystyle { ext{opposite}}=0.213*6} opposite=1.278{\displaystyle { ext{opposite}}=1.278} Interpret your result. The lengths in this problem are in units of kilometers. Therefore, your answer is 1.278 kilometers (0.794mi). The answer to the question is that you must dig 1.278 kilometers (0.794mi) straight down to reach the coal bed.
