    cosine Noun The trigonometric function that is equal to the ratio of the side adjacent to an acute angle (in a right-angled triangle) to the hypotenuse.

    The key is practice. You don't have to relearn your name every day do you? That's because you have been over it and over it until now you know it automatically and will never forget it.

    It is classes for people with learning disabilities. If I were you, I would take charge of my own self and start learning what you are supposed to learn and quit listening to all these people who are telling you that you need medicine and are depressed and all that phsycobabble.

    Well you can obviously learn because you know how to write sentences and spell words. So don't give up on yourself and don't let others define who you are.

    By doing all the stuff your teachers assign and more if that's what it takes to master the material. Quit focusing on learning every little thing and start trying to master the material. If you want to play the piano, it's not enough just to learn the notes. You have to master the music. Take that approach to your studies. And yes, life is hard. It was not advertised as easy.

    Stop telling yourself that it is hopeless. Sounds like you're trying to make it a self fulfilling prophecy. Quit feeding yourself all those negative thoughts. Find Jesus. He will help you.
