[@abaselmi7693]

thank you for your excellence explanations indeed and i will like to ask u that i have problem with this kind of math, (rot2cos(x+pi/4))/cosx. how can i deal with this typ?

[@zodicracker]

How did you come up with sort of 10 on the last problem

[@MarietMarianayagam]

on the last one, then is cos(x)=3/sqrt10? can x be 3/sqrt10

[@shajinimalaichamy]

Could u pls tell me the value of arctan(2) using this method

[@Nooneeee304]

7:47 holysh*t I thought my phone died there 💀💀

[@nabranestwistypuzzler7019]

10:52 But how do you calculate arctan(1/3) if you just want to find out what that is itself? Like I have a problem that’s cos[arcsin(5/13)+arctan(-sqrt(21)/2)], so the trick at the end would’ve even work anyways.

I loved it

[@HowtoDoStuffwithEthan]

how do you figure out on the graph when x is positive?

[@HowtoDoStuffwithEthan]

never mind, I got it
