Problem $1.$ you have a function $f(x)=$exp$(-x^2)$ that you need to integrate over the interval $2,12.$ Using composite trapezoid rule,

a$.$ If the partition of the interval is $n=4,$ write out $($no need to compute the value$)$ the expression of the composite trapezoid rule.

b$.$ Use the code$-$demo on Canvas $($lec $7$ code demo$)$: Composite trapezoid drive.m $($definitely need to modify, you cannot use it as it is b$/$c that's definitely wrong$)$ to compute the numerical quadrature using composite trapezoid rule when the partition of the interval $n=10.$ Attach your code and report the result $($value$).$
