the question goes like this: the first part asks to utilize simulink to obtain the graph pattern: the second part requires us to make use of laplace transform and inverse laplace transform to solve the initial value problem: the third part asks us to compare both the results...

sin x = x - x^3/3! + x^5/5! -+... so does it mean that [(sin x) / x] = 1 - x^2/3! + x^4/5! -+ ...?

what is the taylor's series expansion polynomial for the function f(x) = [(sinx)/x] p/s : i can't open the latex reference, sorry

ok, thanks for the help, i appreciate it very much

u mean like \int\stackrel{1}{0} \frac{sin x}{x} dx = x - \frac {x\stackrel{3}{}} {(3 \cdot 3!)} + \frac {x\stackrel{5}{}} {(5 \cdot 5!)} - \frac {x\stackrel{7}{}} {(7 \cdot 7!)} + - ...?

integrate from 0 to 1, sorry i forgot to include that

no, it's a question that says, compute the integral of (sinx / x) dx by means of a. the trapezoidal rule b. a three term gausian quadrature formulae. c. simpson's 1/3 rule d. determine the integral analytically. i was thinking that part d. uses integration by parts to solve

i don't really understand that article, can u explain it please?

i'm having troubles to integrate \int\frac{sin x}{x} dx could anyone help me with hints? i tried using integration by parts, but i see it as a never ending chain, sin will change to cos... and x^-1 will become -x^-2 and so on
