Statement of the Problem

It is necessary to draw the graph and to show the table for function (the parameters are set by user)

\( y(x)=\sin(\cos(x \mu) \exp(-x/ \mu)), \) \( x \in [a,b], b=a+h. \)

Main Steps:

  • To choose \( a, h, \mu \)
  • To choose curve color
  • To study the behavior of function withdifferent parameters

Example of the Plot without Shiny 

mu <- 3; a<-2; h<-3; color="red"
curve(sin(cos(mu*x)*exp(-x/mu)),a, a+h, n = 1001, 
      col=color, ylab="y(x)")

Example of the Table without Shiny 

 x=seq(a,a+h,by=0.5); y=sin(cos(mu*x)*exp(-x/mu))
 data.frame(x,y)

    x          y
1 2.0  0.4732425
2 2.5  0.1500779
3 3.0 -0.3289449
4 3.5 -0.1475431
5 4.0  0.2206077
6 4.5  0.1323552
7 5.0 -0.1429947
