#differentiation - inverse trig functions

i got the error: thing
bruhh two generals so gay
ok it's not cotθ, but rather cscθsecθ
is the answer 0
i tried using arctan a + arctan b = arctan ((A+B)/1-A*B) formula which would give arc tan of infinity as denominator ends up in a zero value
arc tan of infinity is pi/2
yeah the answer is 0 but i used a rather weird approach
i assumed x/1+x² as t
arctan(t)+arctan(1/t) is π/2
even i had thought of using tan theta by 2 ka formula but that really wouldnt be working here
diff of π/2 is 0 ofc
yeah right
then another approach was to apply d/dx of arctan x + arctan(1/x)
using chain rule
1/1+x² - 1/1+x²
or 0
thanks for the help though
ohh yeah lim x → 0 of n/x
thats longer tbh
yeahh
yeah
narayana moment
lol
