Question

Can someone help me with calculus?

Answer 1

Trapezoidal Rule: \(\Large\frac{h}{2}(y_0+2y_1+2y_2+...+2y_{n-1}+y_n)\)
h = (b-a)/n, where [a,b] is your interval

Answer 2

how do I plug this in?

Answer 3

a = 0
b = pi
n = 4

Answer 4

You will have four different x values, plug them into the equation given to find the y values, and plug those into the formula

Answer 5

Divide the interval into four equal subsections

Answer 6

so you get the x values 0, pi/4, pi/2, 3pi/4, and pi

Answer 7

Small correction: you'll have FIVE (not four) x-values, which determine the FOUR subintervals of the domain [0, pi].

For each of these FIVE x-values, find the corresponding y-value: \[f _{0}, f _{1},f _{2},f _{3}, f _{4}\]

Answer 8

oops, yeah, that's what I meant. Thanks for the correct @mathmale

Answer 9

What does " h " mean to you (coco)?

Answer 10
