Question

HELP PLEASE!

Answer 1

I forgot how to do this....

Answer 2

Would 1/2 be the next value that i would plug in? :/

Answer 3

first one would be a right then second one would be a+ delta x
and then add delta x to the next value

Answer 4

whats a?

Answer 5

and i think you forgot to write 2 with 2nd term
all the middle terms should be double

a=0 \[\int\limits_{a}^{b}\]

Answer 6

one more question \[\cos(x^2) ~~~or~~~ \cos^2(x)\]??
both are different

Answer 7

The first one.

Answer 8

But I think i got lost...

Answer 9

hmm okay so it should be \[\frac{ 1 }{ 8 } [ \cos(0^2) +2 \cos((\frac{1}{4})^2)+2 \cos ((\frac{1}{2})^2)+....]\]

Answer 10

Why 1/4? :3

Answer 11

delta x is 1/4 right
so if a =0
next x value would be delta x +a = 1/4 +0 = 1/4 right ?

Answer 12

OH RIGHT...... I was thinking it as 1/2 because of the 2... dammit. I messed up. xD
I understand now. Thanks. :P
