Hmm... Trigonometry?
anonymous
  • anonymous
i thought i could figure this out using pythagoras theorem but i cant and now im stuck (i have problems remembering things)
Mertsj
  • Mertsj
What is the definition of the cosine of an angle?
ParthKohli
  • ParthKohli
Hmm, I think you need to look up something on trigonometric ratios.
anonymous
  • anonymous
i want to know how to do it but i study and study and never remember anything helpful :( the doctor said that i have depression and it makes me block out things
Mertsj
  • Mertsj
My mother always said that if I would get to work, my depression would disappear.
anonymous
  • anonymous
i dont understand
Mertsj
  • Mertsj
You can easily look up the definition of cosine.
Mertsj
  • Mertsj
What is it?
anonymous
  • anonymous
give me a moment, internets slow today
anonymous
  • anonymous
@Mertsj all i found was something called soh cah toa and i dont know how it helps me at all
Mertsj
  • Mertsj
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.
anonymous
  • anonymous
well i didnt know you wanted me to find that :(
Mertsj
  • Mertsj
That is the definition of cosine
Mertsj
  • Mertsj
So now, apply it to your triangle.
anonymous
  • anonymous
i knew that but how do i use cosine to solve this triangle
Mertsj
  • Mertsj
What is the acute angle that you know?
anonymous
  • anonymous
24
anonymous
  • anonymous
cosine of 24?
Mertsj
  • Mertsj
What is the side adjacent to that angle?
anonymous
  • anonymous
11
anonymous
  • anonymous
cos(24) = 11/x
Mertsj
  • Mertsj
Solve that.
Mertsj
  • Mertsj
Yep.
Mertsj
  • Mertsj
That was pretty easy, wasn't it?
anonymous
  • anonymous
thank you so much :D the only problem is that this is what happens EVERY time i have an advanced math problem is that i have to relearn it every time
Mertsj
  • Mertsj
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.
anonymous
  • anonymous
well, my mom sent me to remedial math classes and they made me repeat over and over and it didnt work :( i started not learning things around 11 or so and the remedial class gave up on me and suggested a special education and pills for depression anxiety. what is special education
Mertsj
  • Mertsj
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.
anonymous
  • anonymous
medicine didnt work, i try learning what im supposed to i study for at least 4 hours at a time
Mertsj
  • Mertsj
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.
Mertsj
  • Mertsj
And quit studying for 4 hours at a time without a break.
anonymous
  • anonymous
i dont know because my doctor said that i "stopped" learning when i was 11 how does a person stop learning
anonymous
  • anonymous
then how do i study the right way
Mertsj
  • Mertsj
Did you stop learning?
Mertsj
  • Mertsj
How old are you now?
anonymous
  • anonymous
i cant really say how old i am lets say around 19-21
Mertsj
  • Mertsj
Have you learned anything in the last 10 years?
anonymous
  • anonymous
well all i "learned" is what i have to deal with all the time im forgetful and feel stupid and i always am sad about nothing
Mertsj
  • Mertsj
Do you drive a car?
anonymous
  • anonymous
your right i DID learn to drive a car o_- but i learned to drive a car when i was little (on our driveway and my father told me the road signs and things) weird..
Mertsj
  • Mertsj
No one learns to drive in a driveway. You have to drive on a road to learn to drive.
anonymous
  • anonymous
well i dont know then :( the doctors cant figure out whats wrong i hate the doctors, we stopped going years ago.
Mertsj
  • Mertsj
There's nothing wrong. Get that out of your head and get on with your life.
anonymous
  • anonymous
well how do i learn school things, im still in hs :(
anonymous
  • anonymous
i try to get on with my life but its so hard. is there something i can do to help this? i tried every remedial class in the book but i am stuck relearning things over and over
Mertsj
  • Mertsj
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.
anonymous
  • anonymous
i can play the piano, i can't learn geometry and algebra. i tried tutors and books and the internet and i hardly get anything out of it ever. i only learn a little bit of anything and then nothing else its like my brain is full of nothing
Mertsj
  • Mertsj
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.
anonymous
  • anonymous
I would but theres a reason i cant do that -_-
Mertsj
  • Mertsj
There is NO reason you can't do that. Seek and you shall find.
