Question

Help Please. I need some help. :/

Answer 1

Trapezoidal Rule\[\Delta x = \frac{ b-a }{ 2n } = \frac{ 1-0 }{ 2(4) } = \frac{ 1 }{ 8 }\]

Answer 2

\[x _{0} = 14\cos(0)^2 = 14(1) = 14?\]
Thats what i put and got it wrong.

Answer 3

but you need use the trapezoidal rule what is wrote above of this integral of 14cosx^2 dx

you need using this formula and evaluate this integral of 14cosx^2 dx in this form

Answer 4

next to delta x / 2 there are [f(x_0) +2f(x_1) +.... till n=4
and this will be your right answer

Answer 6

It says to enter an exact number

Answer 7

so the first inteval is
