Hi guys, i was given the following problem: The mean diameter of a batch of bolts is 9.711mm and the standard deviation of the batch is 0.126mm The tolerance for this batch of components is 9.73mm to 9.97mm. In a batch of 2000 bolts, determine the following: a) The percentage of bolts...

I think i had my calculator set in the wrong mode... I switched it to 'RAD' and it came up 0.5403

0.999847695

X = 1 substitue: = 1 - (1/2x1^2) + (1/24x1^4) - (1/720x1^6) = 1 - (0.5) + (0.041666..) - (0.0013888...) = 0.5402778 ?

X = 5 substitue: = 1 - (1/2x5^2) + (1/24x5^4) - (1/720x5^6) = 1 - 12.5 + 26.041666... - 21.7013888... = - 7.159722 What does this mean? (My maths teacher was a Media teacher)

I'm trying but I'm not understanding what I should be seeing at the end of my calculations.

"The next step is to check to see that it approximates the cosine. Calculate the cosine of some angle t and then evaluate that series of 4 terms where x = t." How do I do this? This is the part I am unsure about.

This is what i have so far: http://putfile.com/pic.php?pic=main/8/22414282061.jpg&s=f10 This (i think) is the 4 terms. I do not know what to do after this

Ok, i got this far: http://putfile.com/pic.php?pic=main/8/22414282061.jpg&s=f10 This (i hope) is the 4 terms, i do not know what to do after this.
