((USING MATLABB))

Given two differential equations X =tsin( pi*0.872*sin(t)/t) and

Y = -|t|* cos(pi * sin(t)/t) where -pi

1. Write script to plot X and Y with writing after plot command fill(X,Y,'r')? (script_Q1_1)
2. At the same figure by using hold command plot X and Y when

X =tsin( pi*0.7*sin(t)/t) with writing after plot command fill(X,Y,'w')? (script_Q1_1)

3. At the same figure by using hold command plot X and Y when X =tsin( 0.7*sin(t)/t) and Y = -|t|* cos(sin(t)/t) with writing after plot command fill(X,Y,'m')? (script_Q1_1)
