lol the longer this question remains here the longer i begin to suspect its retardness. Anyway, On this site if you scroll to the bottom and read the last paragraph, more specifically the information regarding "(d)" QUOTE"" Even though wehave no formula for the area of a funny shape like...

OK I have a v-t graph and I wish to find the change in displacement/distance/position w/e. REFER TO THE PICTURE FOR THE ACTUAL QUESTION THANKS! (see the pic attached) My teacher taught me a method of seperating the LINE (ref.picture) into segments then calculating the area of each one then...

Haha, there we go, that's why i was still getting -1. And thanks for the inspirational words dexter...lol, anyways tommorow at school I am just going to tell my teacher the truth how i got the formula and i'll just ask him to explain how i can attain it, thanks for the help guys.

In my calculator (-1)^2= -1 but if i do -1 x -1 then it gives me 1 which is correct. why does my calculator give me the wrong answer lol. But i still don't know how to get the formula...

Yes that is the sequence that my teacher gave me, thanks for your formula I am trying it now and so far for the first term it is correct, I am hoping it will work for all the other I am checking now* But i still have a question, can you tell me how you got that formula? EDIT: DAMN! for n=2...

edit: nvm nvm nvm

Alright well i tried your equation and it didn't work out for me but there is a high chance it's because i didn't do it correctly, can you correct me where i went wrong: an = (-)^n+1 x 2^n / 1+2(n-1) <--original. a1 = (-)^2 x 2^1 / 1+2(1-1) a1= -2/3(0) a1=-2 You see I am not really sure...

heh, damn I wish math professors/teachers would see my post. I even wouldn't care if it was MY math teacher because at least he'd see how hard I am trying, lol.

hmm that's very interesting you see our teacher hasn't taught us yet that we can use 0+2+2 as a common ratio or common difference, i thought it had to be one single value..hmm But if i follow what you said then i need a pattern for the top one which is 1,2,-4,8 which using your method could...

yeah that's all my teacher gave me

Yes that is what I am saying.

My teacher gave me a bonus question, and I really want to understand this and impress him lol. The current unit we are studying involves arithmatic/geometric sequences The question: We have to find the 10th term of: 1/1 , 2/1 , -4/3 , 8/5 ... I want to understand this so please don't...
