Integration of cotx (2 Viewers)

Re: 回复: Re: Integration of cotx

Will you be required to integrate those sorta trig identities in 2U course?

I'm pretty sure 2 unit is just sin cos and tan. I didnt come across anything harder than that when I did 2 unit last year.

But um....3U is when you start encountering such trig integrals?

Oh is it. I completely forgot, I was just thinking back to what I learnt last year, even though I learnt some 3U stuff as well

No...my post above was worded really shit-ly.

I know in 2U, you integrate/differentiate sin/cos/tan. But I'm just wondering, for the harder ones such as secx or cot^2 x etc.
Sorry for the confusion...

nah those integrations are more 4 unit kind of things. but i guess they could if they led you into it by using a first part of the question
