Now, unless I can enlist the integral 1/3x^3, it will not be feasible to calculate arclength by constant estimates

So, what I need is to utilize the area 1/3x^3 to be able to go from 1.414 to 1.47 

The area is .333 

Somehow, that area is going to yield that extra .06 I need to go from 1.414 to 1.47

Heron's formula is no use Re: 2utilize the area .333 in Y=x^2

Alright, easy enough to see I need the lengths of A, B when I have C as 1.414 


___C____1 
\  A       / 
   \     /B 

C length is 1.414 for Y=x^2 box with C as diagonal. The function x^2 area is 1/3x^3 is .333 

Area for under C is .500 and length 1.414 

What I need to do is get where A+B = 1.47 a difference of .06 

Now looking at Heron's formula Area = sqrt[S(S-A)(S-B)(S-C)] where S = (A+B+C)/2 is not going to give me anything because although I know the area is .5-.333 = .167 and know C=1.414 is of no help. 

What I need is a height in general, for I know that A+B is a bit larger than 1.414 and hopefully is 1.47

Let me try it on Y=x^3, integral is 1/4x^4 

1.414   is to A 
_____           ____ 
.5                 .25 


1.414*.25  = .5A 

.3535 = .5A 

A = .707 

Subtract from 1 we have .3 


1.414+ .3 = 1.71 

Is that the arclength of Y= x^3 in interval 0 to 1 

??

In reply to#416740
In something like Y=x^10, I could see the arc length in interval 0 to 1 being a tiny tiny bit bigger than 2. say 2.01, but not no 2.4

Alright the Quarter circle area is .785

So we have

1.414  is to  A
______         ____
.5                 .285

The .285 is .785-.5


So we have

.402/.5 = A

.805 = A

Subtract from 1 we have .2

So add .2 + 1.414 = 1.61

Not bad, not bad at all for the quarter circle is arclength 1.57

So it appears the method is valid, quick, easy. And what I like most of all, the mind is in full comprehension of each step and knows what is going on. No-one in Old Math can say that with their thousands of obnoxious tricks and trig you have to shovel. Does anyone know why math professors love shovelling tricks and trig?
