from 0 to infinity and this is going to give me a this

Part c you're given that f of t is equal to 2 cosine of omega

Uh if you look at i1 of T if you set tal to zero this two terms cancel each other because cosine of - 3un / 4 is

This is well know right and we know FN was

So it has a f of key and then if you modulate it by this strange function n is = to

And I forgot to mention that the height of this triangle is

Sides this J cancels then you have U uh let me see J squ is minus

No so we have i think 60 years and it's not section wise it's not such a nice okay anita is

... Square Omega t with does anybody remember the trigonometric identity for cosine of square of Thea

And if you were to ask what the resistance is when they're connected in parallel okay the rp that you see in this node here is

Fact and I can work out the detail for you if you want to work out BC okay BC is equal to

Sources somewhere and another voltage source to but many other

If you the clock a bar H of Omega magnitude and then this is omega over omega squared plus
