In one sentence, describe what the following article is about: You'll need a decent rail to grind on before you learn this trick. Look for rails over five feet long, preferably close to the ground. Local skate parks often have grind rails made just for tricks, so check there. You can also grind on curbs, but they'll need to be painted or waxed. Start about 10 feet away from the rail, or as far away as space allows. Push off and get some speed, making sure to line up your feet in their correct stance. Stay relaxed as you get closer to the rail. Once your front wheel is even with the rail, jump up and towards the rail. Jump as you normally would, crouching down and springing up to get a lot of height, but spring slightly towards the rail so you can position yourself over it. More height isn't necessarily better here, just jump high enough to get over the rail. Let gravity pull you and your scooter down to the rail. You'll want to land so that the bottom of your deck lies across the railing, either perpendicular or at a slightly smaller angle. Keep your foot position solid as possible, which will make balancing a lot easier. The momentum that you built up will carry you across the rail, pushing you forward to "grind" along it. Keep your balance by actively shifting weight either left or right. Your foot placement will be essential here, because your feet are anchoring you to the deck and to the rail. It might take a couple of practice runs to get comfortable balancing. You can either ride to the end of the rail or jump off mid-rail; it depends on your preference or any trick combo you have in mind. Pick your point to jump off, then plant your feet firmly on the deck. Continue to maintain your balance, then perform the simple jump up and out away from the rail. Don't make this a super high jump: you only need it to clear the rail a bit and make sure your wheels don't get caught on it. Land the trick with solid foot placement, keeping them in the same places they were when you jumped from the rail. Bend your knees to absorb the shock of landing. Correct for any changes of handlebar positions, then continue on.
Summary: Find a rail. Get some speed. Jump up. Land on the rail. Slide on the rail. Jump off. Land.

In one sentence, describe what the following article is about: Trigonometric concepts are all related. It is best practice to keep all of your notes in one place so that you can refer back to earlier notes. Designate a specific notebook or binder to your trigonometry studies. You can also keep practice problems in this book. Avoid using your class time to socialize or catch up on homework for another class. When you are in trigonometry class, you should be zeroed in on the lecture and practice problems. Write down any notes that the instructor puts on the board or otherwise indicates as important. Volunteer to solve problems at the board or share your answers to a practice problem. Ask questions if you don't understand something. Keep communication as open and fluid as your instructor will allow. This will facilitate you learning and enjoying trigonometry. If your instructor prefers to lecture mostly uninterrupted, you can save your questions for after class. Remember it is the instructor's job to help you learn trigonometry, so don't be shy. Complete any homework assigned. Homework problems are good indicators of test questions. Make sure that you understand each problem. If no homework is assigned, work problems from your book that reflect the concepts covered in the most recent lecture.
Summary: Write in the same notebook. Make trigonometry your priority in class. Remain engaged in class. Follow up with more practice problems.

In one sentence, describe what the following article is about: Retinoids are a form of vitamin A which will reduce the amount of hypertrophy to your sebaceous glands. You can find over-the-counter acne preparations with lower doses of retinoids than you'll get from a prescription. However, many people respond to the over-the-counter strength products well and do not need prescriptions. Ask your doctor if you need a prescription or if over the counter is a better option for you. Women with bad acne have the option to use oral contraceptives to control their hormonal levels. This also has the advantage helping to balance other secondary effects of the hormones, such as irritability and water weight gain. You need a prescription to get contraceptives that affect your hormones. Don't use oral contraceptives if you are pregnant or trying to get pregnant. Accutane is an anti-acne medication for treatment of severe acne and requires a prescription. If you have sebaceous gland hypertrophy or severe acne, ask your doctor if Accutane is right for you. You will need to have your blood monitored every month while taking the medication and may experience side effects for several months after using it. Do not use Accutane unless you fully understand the risks of the medication. Accutane can have long-term effects on your health and wellness. You cannot take Accutane if you are pregnant or planning to become pregnant. Phototherapy is a treatment option you can perform at home by purchasing special equipment, or you can choose to ask your dermatologist. Research supports this treatment, which is simple and easy to perform. Technically, exposure to sunlight is phototherapy. However, in climates where the sun doesn't shine enough hours or you can't get outside when the sun is out, you can purchase a phototherapy unit. Use the unit to treat your acne as directed and using the safety precautions listed on the unit. Possible side effects from using these units include skin that becomes red, peels or changes skin tone. Your doctor may also perform photodynamic therapy in the office. This involves applying a medication to the skin, which is then activated by a special light. This is more effective than a light treatment alone. Oral and topical antibiotics may be used to treat acne, especially when reinfection is a concern. Topical antibiotics can be used long-term, usually along with benzoyl peroxide or retinoids. Oral antibiotics are usually used short-term to get a bad breakout under control. Antibiotics are especially useful for inflammatory acne, which is acne with a lot of red bumps, pimples, or cysts.
Summary:
Consider prescription retinoids. Consider oral contraceptives. Ask about Accutane. Ask about phototherapy. Talk to your doctor about antibiotics.
