Problem: Article: Always wanted to head out on a round the world trip for a year? Dreaming of a beach and some palm trees in Jamaica, or world class art in Paris? Exploring a new environment and exposing yourself to new experiences can really help to energize and excite you. Many airlines offer round the world tickets. You can also book tours and arrange your accommodations in your destination with a few clicks of your mouse. The hardest thing you'll have to do is fit your clothes in a carry on and get to the airport on time. Solo travel can be a good way to challenge yourself in a new place and discover traits you didn't know you had. Coping with a foreign language in a foreign city or country alone can be challenging. But it also allows you to be more open to meeting new people and trying out new experiences. Another great way to travel is to contact a friend who lives in another country and arrange a visit. In a new place, there is nothing better than a friend who can act as your tour guide and show you the best restaurants,sites, and experiences. This is also a great way to reach out to a friend and do something fun or exciting with them. Maybe you just don't have enough time or money to go on a trip across the ocean or to another country. A cheaper alternative to air travel is a road trip around your area or home state, with friends or alone. Road travel also allows you to plan your trip based on the sites you want to see and experience. World's largest paper clip? Check. The Voodoo Museum in Louisiana? Check. Create your own tour of the area and map it out. Get excited about planning a custom trip without having to worry about baggage fees or a language barrier.
Summary: Book a ticket to your dream destination. Visit a friend in another country. Go on road trip through your home state or area.

Problem: Article: Choose the best shoes for where you'll run. Road shoes for the road, trail shoes for rougher terrain: this will keep your feet protected and help with traction. Account for your arches. You'll need more or less support, depending on how high of an arch you have. The shape of the shoe itself will also need to change. Go to your local major shoe store to get help with this. Check your heel movement. Some people roll their heels, either out or in, as they run. This will also affect the type of shoe you need. Check some old shoes for wear to get an idea of how you move. Tie your shoes correctly. Did you know you can lace your shoes differently to make them fit better? There are methods to create more space in the toes, or support high arches. Even ways to keep heels in place if they tend to slip! Get the right size! Correct fit is key in making sure your shoes are as comfortable as possible. Even if you think you know what size you are, be willing to be wrong because it can make a huge difference in how you feel afterwards. Shoot for good movement. You should be choosing clothes that are loose or flexible, so that they allow for a good range of movement. You'll also want clothes in shapes and materials that breathe well. This can help reduce rashes and other skin problems. Factor in weather and temperature. You'll probably need more than one jogging outfit (depending on where you live). Have clothes that are warmer and provide more coverage for if you go running in the winter, for example. Don't forget about pockets. You'll want pockets in order to carry important things like your ID and your keys. Alternatively, though, you can use other things like your shoes or an armband. You'll also want to wear the right kind of socks. Look for socks specifically marketed for runners. This can help prevent blisters. Get an mp3 player. Smaller players, like an iPod nano, are great for using while you're jogging. There are even several wristbands that they can be fit into. Find something to listen to. Music is the obvious choice, but you could even get something like a podcast or audio book too. This can be a great way to stay in touch with the news or fit in some "reading" if you're low on time. Enjoy the quiet if you prefer: you don't have to listen to anything if you don't want to! Stay safe! If you do choose to listen to something, try to only have one ear bud in. Hearing an approaching car or other sign of trouble is crucial to your safety.
Summary: Get the right shoes. Buy comfortable, appropriate clothes. Consider some entertainment.

Problem: Article: Let's say you're working with the following problem: Y =(x-7) You cannot take the square root of a negative number, though you can take the square root of 0. So, set the terms inside the radicand to be greater than or equal to 0. Note that this applies not just to square roots, but to all even-numbered roots. It does not, however, apply to odd-numbered roots, because it is perfectly fine to have negatives under odd roots. Here's how: x-7 0 Now, to isolate x on the left side of the equation, just add 7 to both sides, so you're left with the following: x 7 Here is how you would write it: D = [7,) Let's say you're working with the following function: Y = 1/( x2 -4). When you factor the denominator and set it equal to zero, you'll get x = (2, - 2). Here's where you go from there: Now, check the area below -2 (by plugging in -3, for example), to see if the numbers below -2 can be plugged into the denominator to yield a number higher than 0. They do. (-3)2 - 4 = 5 Now, check the area between -2 and 2. Pick 0, for example. 02 - 4 = -4, so you know the numbers between -2 and 2 don't work. Now try a number above 2, such as +3. 32 - 4 = 5, so the numbers over 2 do work. Write the domain when you're done. Here is how you would write the domain: D = (-, -2) U (2, )
Summary:
Write the problem. Set the terms inside the radicand to be greater than or equal to 0. Isolate the variable. State the domain correctly. Find the domain of a function with a square root when there are multiple solutions.
