Rear Cassette 10 Speed from 11-36 to 11-40

I do alot of hill climbing to get to work on my Calibre Bossnut V2, and saw a Cassette with 11-40T, would this make it a little easier climbing up the hills.
I have 20 gears 2 x 10, 22 x 36 on the front and 11.-36 on the rear.
By adding the 11-36 Cassett would I need to add extra chain links as I'm replacing the chain shortly due to wear.

Search YouTube for tutorial videos. There are plenty on there. The largest sprocket - largest chainring and add 2 links method usually works for me.

My wife’s Giant Toughroad is equipped with an 11-42T cassette and 32/44 chain set as standard and it works just fine.

22 + 11 = 33
76 - 33 = 43t derraileur capacity required.
shimano deore shadow long cage has a capacity of 43t so it will be ok. The maths says its not as extreme as i thought !
Still a bit too flappy chain for my liking !
As I said in my previous post, search YouTube for tutorial videos.

Choose the biggest gear on the front and the biggest on the back.
Adjust the chain length so that the mech arm is pointing forward at 45 degrees
One last check, fully compress the rear suspension. If you cannot because the chain is too tight then lengthen the chain and check again. This step is important on a full suspension bike.
The reason for the last check is that some bike geometry designs extend the rear centre and if the chain is not long enough to cope with this extra, you may suffer severe damage to the rear mech.
