Problem: Article: You should adjust your bedroom environment so that it gets nice and dark by, for instance, closing the curtains and turning off all the lights. You should also turn off computers, printers, stereo systems, video game consoles and any other electronic devices in the room. The buzz and light of electronic devices can disturb your ability to fall asleep. Go outside in the morning to get some light in your eyes. In the evening, turn down your lights and close your blinds to block out any artificial light. Experiencing light during the morning and daytime and darkness at night will help to reset your natural rhythm and improve sleep. If you live in a place without much light in the winter months, you could try a light box. Use the light box for thirty minutes every morning. You may want to experiment with white noise, especially if there is a lot of background noise in your house or neighborhood. White noise can cover up bothersome noises that would otherwise wake you up during the night. Try leaving a fan or a humidifier running during the night. If this doesn't work or is not appropriate for your situation, you could try a white noise machine specifically designed for sleep. White noise machines range in price from $20 $100. You can purchase white noise machines online or at home and beauty stores. Aromatherapy is an alternative medicine that uses scents from essential oils to treat various conditions. You breath in scents such as lavender, which impacts the system that regulates your mood and emotion. Put a few drops of an essential oil into a humidifier, your bath or an essential oil diffuser. Try one of the following oils that are good for sleep and relaxation: Lavender Lemon Bergamot Ylang Ylang Sage Jasmine
Summary: Make the room dark, quiet and free of electronics. Explore light therapy. Use a white noise machine. Try aromatherapy.

Problem: Article: As your body becomes more fit and acclimated to your elliptical workouts, you can increase the intensity of your workouts using the console. Consult with a personal fitness trainer or expert regarding an optimal workout routine based on your personal fitness. A trainer may recommend an ideal frequency at which you should use the elliptical machine.
Summary: Pedal on the elliptical machine consistently for between 20 and 30 minutes. Train using the elliptical exercise equipment at least 3 times per week.

Problem: Article: A wide or broad rule of law may apply to all types of different factual situations that are similar to the case at hand. In contrast, a narrow or limited rule of law may only apply to a certain set of circumstances. Some court decisions address a point of law using very broad, generalized principles that can apply to a variety of factual situations. For instance, suppose a case established a rule of law that the Uniform Commercial Code applies to the sale of all motor vehicles. If the precedent case dealt with a truck, a court that later had a similar case involving a car rather than a truck would still follow the same rule of law. Other decisions are very fact-specific and restricted only to the case in which the rule is stated. A narrow rule of law gives courts the ability to distinguish similar cases based on slightly different facts from the precedent. If a rule of law only applies to a very specific factual situation, then courts won't be necessarily bound to reach the same result in cases in which the facts vary somewhat. The court decision will often state that its ruling is limited to a certain set of facts if it is intended to be a narrow rule of law. Otherwise, if the case is not too fact-specific, it is likely to be a broader rule of law. A broad rule of law will encompass many cases and fact situations because it is not limited to a particular set of facts. A narrow rule of law may only ever apply to a single case and set of circumstances.
Summary: Note that the ratio decidendi may be expressed in wide or narrow terms. Determine whether the rule of law in your case is broad or narrow. Realize that a broad rule of law will tend to apply to many more cases than a narrow rule of law.

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.
