Question

IF X=18 (+ or -) 0.5 and Y= 9.0 (+ or -) 0.4, find appropriate values, including errors, for:

X+Y

X-Y

X+2Y

2X-3Y

X * Y

X / Y

sqr(XY

XY^3

Answer 1

hold on

Answer 2

If we wanted to include the endpoints we would write [2,4]. If we wanted to ...... \frac{1}{xy^5}. 35. \sqrt{x^2y^4}. xy2. 36. \bigg(\frac{8x^6}{y^4}\. \frac{2x^2}{y^{4/3}}

Answer 3

2.5 Mean Square Approximation and Parseval's Identity 16 .... ((x + 3)( U−3 − U−2) + (2x + 5)( U−2 − U−1) + (x + 4)( U−1 − U0) ... 18 x cos 3x + ∑. 6 n=1, n=3 sin nx n(9−n2) . # 49: yp = ... ↔ yp = x(.... # 67: y = − .... Same reasoning as in the previous exercise, we find the solution ...... So u(xy) = T if and only if 2xy = T if and only

Answer 4

do u get it?

Answer 5

this doesnt make any sense, are you sure your doing it the right way

Answer 6

yep

Answer 7

here let me put it another way

Answer 8

all we have to do is add X +Y for the first one

18 + 9.0 = 27 then do you just add the uncertainties? .5+.4= .9

27 + or - .9 ???

Answer 9

If we wanted to include the endpoints we would write [2,4]. 2.5 Mean Square Approximation and Parseval's Identity 16 .... ((x + 3)( U−3 − U−2) + (2x + 5)( U−2 − U−1) + (x + 4)( U−1 − U0) ... 18 x cos 3x + ∑. 6 n=1, n=3 sin nx n(9−n2) .

Answer 10

Same reasoning as in the previous exercise, we find the solution ...... So u(xy) = T if and only if 2xy = T if and only

Answer 11

No this is none of that, this is physics lol

Answer 12

is my answer correct?

Answer 13

Of course. yes yes yes

Answer 14

ok so you add the uncertainties?

Answer 15

yep

Answer 16

x+2Y = 36 + or - 0.9??
