Answer:
the rise over run. if a ramp has a slope of 1 the rise over one is most likely 1/1
Step-by-step explanation:
The differences between the trapezoidal rule and simpson's rule is -
The trapezoidal rule and Simpson's method, the latter a set of formulas of varying complexity, are both Newton-Cotes formulas, that are used to examine and model complex curves.
<h3>What is
trapezoidal rule?</h3>
The trapezoidal rule is just an integration rule that divides a curve into small trapezoids to calculate the area under it. A area under the curve is calculated by adding the areas of all the small trapezoids.
Follow the steps below to use the trapezoidal rule to determine the area under given curve, y = f. (x).
- Step 1: Write down the total number of sub-intervals, "n," as well as the intervals "a" and "b."
- Step 2: Use the formula to determine the width of the sub-interval, h (or) x = (b - a)/n.
- Step 3: Use the obtained values to calculate this same approximate area of a given curve, ba f(x)dx Tn = (x/2) [f(x0) + 2 f(x1) + 2 f(x2) +....+ 2 f(n-1) + f(n)], where xi = a + ix
<h3>What is
Simpson's method?</h3>
Simpson's rule is used to approximate the area beneath the graph of the function f to determine the value of the a definite integral (such that, of the form b∫ₐ f(x) dx.
Simpson's 1/3 rule provides a more precise approximation. Here are the steps for using Simpson's rule to approximate the integral ba f(x) dx.
- Step 1: Figure out the values of 'a' & 'b' from interval [a, b], as well as the value of 'n,' which represents the number of subintervals.
- Step 2: Determine the width of every subinterval using the formula h = (b - a)/n.
- Step 3: Using the interval width 'h,' divide this same interval [a, b] [x₀, x₁], [x₁, x₂], [x₂, x₃], ..., [xn-2, xn-1], [xn-1, xn] into 'n' subintervals.
- Step 4: In Simpson's rule formula, substitute all of these values and simplify. b∫ₐ f(x) dx ≈ (h/3) [f(x0)+4 f(x1)+2 f(x2)+ ... +2 f(xn-2)+4 f(xn-1)+f(xn)].
Thus, sometimes we cannot solve an integral using any integration technique, and other times we don't have a particular function to integrate. Simpson's rule aids in approximating the significance of the definite integral in such cases.

Answer:
1/2
Step-by-step explanation:
Answer:
Two tailed t = 2.797
One tailed t = 2.492
Step-by-step explanation:
The t-value can be defined as the ratio of the difference between the mean of the two sample sets and the difference that exists within the sample sets.
t at 99% confidence interval. For;
degree of freedom df = 25-1 = 24
Two sided test
t ( 99% +1/2% = 99.5)
Check t at 0.995 df = 24
t = 2.797
One tail test
t ( at 0.990) df = 24
t = 2.492
Answer:
Step-by-step explanation:
The period of a trig function tells you how much space is taken up by one "up-down-up" of the graph, which is a revolution. Because half of this graph takes place in a span of 2π, then the whole graph will span 4π.
