Question

Define an even periodic extension of

 

f(t)=2+4t,     0<t≤4f(t)=2+4t,     0<t≤4

 

and hence find its half-range cosine series representation in the form

 

FS(t)=a0/2+∞∑n=1an cos(nπt/4) 

 

Compute a0,a1,a2,a3a0,a1,a2,a3 correct to three decimal places and enter the values in the appropriate boxes below.

 

AA: Enter a0a0 correct to 3 decimal places: 
BB: Enter a1a1 correct to 3 decimal places: 
CC: Enter a2a2 correct to 3 decimal places: 
DD: Enter a3a3 correct to 3 decimal places:
