Question

Set up the integral that gives the length of the graph y = sin x from x = 0 to x = π.

Answer 1

tu find length av a kerv, yu integrate along the kerv

integral from a tu b av [1+(dy/dx}^2]^1/2

y=sine(x)  ....dy/dx=kosine(x)

so integrate sqrt[1+kosine^2]

as far as me no, dont hav a simpel integral av this

gota take bunch av small steps & approx kerv leng=diagonal at top av small part av kerv

Yu oenlee need tu go from 0 tu pi, then multipli than anser bi 2

me get approx anser=7.640395578
