It is extremely important that you are taking care of yourself during difficult times so that you can stay rejuvenated and healthy. Even if sleeping seems difficult try to make sure you are taking time to at least lie down with your eyes closed and resting. Honor that your body and mind are working overtime to get you through a stressful situation and that you need time to rest and heal. Some people respond to stress by undereating or overeating. Your journal can come in handy to keep track of what you are eating. There are also apps you can use on your computer or mobile device to make sure you are getting enough calories and also not over-indulging because of stress. Eat healthy foods that are good for your body and brain such as fruits, vegetables, protein, and healthy grains. Getting some level of movement will help clear your head and reduce your stress. Even a 10 minute walk can help relieve tension and stress. Dancing can also help physically and emotionally. Walk up and down steps for 10 minutes. Take a small run. Do something active to get your blood pumping and to relieve your stress. If you have friends or loved ones that you can trust, lean on them to help you through your situation. Let them know you need help and need to vent. Keeping calm during tough times can be overwhelming. You may feel as though you can't handle your emotions, or as though you are exploding at other people. You may be having significant trouble sleeping. If you don't feel in control, it may be time to seek the help of a therapist. If you have persistent feelings of depression, sadness, or hopelessness interfering with your ability to perform your daily functions, talk with a therapist. This person can help guide you, helping you find the calmness you need.

summary: Get plenty of rest. Have healthy eating habits. Get some exercise. Use your support system. Consider seeing a therapist.

The unit vector of a vector A is the vector with the same initial point and direction as A, but with a length of 1 unit. It can be mathematically proven that there is one and only one unit vector for each given vector A. This is the process of identifying the unit vector for a given vector A. A bound vector in Cartesian space has its initial point at the origin of the coordinate system, expressed as (0,0) in two dimensions. This allows you to identify a vector solely in terms of its terminal point. By restricting ourselves to bound vectors, A = (x, y) where the coordinate pair (x,y) indicates the location of the terminal point for vector A.

summary: Define a unit vector. Define the Normalization of a vector. Define a bound vector. Describe vector notation.

Golden retrievers love to fetch, and it is a great way to exercise them. You probably won't need any help getting your puppy to chase a ball or toy. But be sure to instill good habits early on to make sure they learn how to bring the toy back and drop it near you. Throw one, and when your dog picks it up, show the other toy and throw it the other way. While he is chasing it, pick up the first toy. Do this until he is accustomed to fetching and then running towards you. Eventually, you can call your dog without showing the second toy. If he comes, say drop it and show the second toy. When your dog will drop on command, you can eliminate the second toy. When your dog picks it up, shake the line and run away to encourage him to follow you. If he follows give a treat. If your dog still runs away, reel him in with the rope. Praise and reward when close. Don't always throw the toy right away. Let your dog chew on it sometimes after returning. You don't want him to think he will lose it every time he returns. After a few weeks, your dog should stop trying to escape with the toy. Say "drop it" and put a treat right in front of your dog's nose. This will get even the most stubborn dogs to give up the toy. If your dog still won't drop, try a more irresistible treat, like bits of bacon or cheese. Eventually you will not need the treat, but still give one every so often. Just before your dog drops the toy, say "bring it" and move away. When he reaches the place you were standing, say "drop it" and walk back to him to pick up the toy. It may take a few weeks before your dog learns to bring the toy to you. Tell your dog to sit and stay when he drops the toy. If your dog tries to grab it when you bend down, immediately say "no" or "uh, uh" and stand up. Eventually, your dog will figure out that if he wants to keep playing, he will have to sit and stay while you pick up the toy. When he does hold the stay, remember to say "okay" to release him before you throw the toy again.
summary: Start with good habits. Use two toys to teach your dog to bring the toy back. Attach a line to the toy if using two toys doesn't work. Use treats to get your dog to drop. Walk away to teach your dog to drop closer to you. Use "sit" and "stay" to keep your dog from picking the toy up when you reach for it.
