the instructions for the given integral have two parts, one for the trapezoidal rule and one for simpsons rule. complete the following parts.\n int_{3}^{13} \frac{1}{s^{2}} d s \ni. using the trapezoidal rule\na. estimate the integral with ( n = 4 ) steps and find an upper bound for ( left|e_{t}\right| ).\nthe estimate using the trapezoidal rule with ( n = 4 ) is\n(round to four decimal places as needed.)
Answer
Explanation:
Step1: Calculate (\Delta s)
The formula for (\Delta s=\frac{b - a}{n}), where (a = 3), (b = 13), (n=4). (\Delta s=\frac{13 - 3}{4}=\frac{10}{4} = 2.5)
Step2: Find the sub - intervals
The sub - intervals are (s_0=3), (s_1=3 + 2.5=5.5), (s_2=5.5+2.5 = 8), (s_3=8 + 2.5=10.5), (s_4=10.5+2.5 = 13)
Step3: Calculate (f(s)) at each sub - interval
(f(s)=\frac{1}{s^{2}}) (f(s_0)=\frac{1}{3^{2}}=\frac{1}{9}\approx0.1111) (f(s_1)=\frac{1}{5.5^{2}}=\frac{1}{30.25}\approx0.0330) (f(s_2)=\frac{1}{8^{2}}=\frac{1}{64}\approx0.0156) (f(s_3)=\frac{1}{10.5^{2}}=\frac{1}{110.25}\approx0.0091) (f(s_4)=\frac{1}{13^{2}}=\frac{1}{169}\approx0.0059)
Step4: Apply the trapezoidal rule formula (T_n=\frac{\Delta s}{2}[f(s_0)+2f(s_1)+2f(s_2)+2f(s_3)+f(s_4)])
(T_4=\frac{2.5}{2}[0.1111 + 2\times0.0330+2\times0.0156+2\times0.0091+0.0059]) (=\frac{2.5}{2}(0.1111+0.0660 + 0.0312+0.0182+0.0059)) (=\frac{2.5}{2}(0.2324)) (=2.5\times0.1162) (=0.2905)
Answer:
(0.2905)
