Question

pls help trignometry question

Answer 1

which
one?

Answer 2

all of them @UnkleRhaukus just want to check if the answer is right or not

Answer 3

A and D are correct

Answer 4

\[ \lim_{x\to \pi ^-}( \cot x) =-\infty \]

Answer 5

my bad thought it was tanx not cotx

Answer 6

For D

Answer 7

All good except E

Answer 8

@.Sam. SO A and D are right what about b and c and e

Answer 9

\[ \lim_{x\to \left(\frac{\pi }{2}\right)^+} ( \tan x) =-\infty\]

Answer 10

So @.Sam. which all have i done right

Answer 11

All good except for E

Answer 12

So how do we have to do e

Answer 13

@u0860867
i think you found
\[\lim_{x\to\pi/2^-}\tan x=\infty\]

but the question is
\[\lim_{x\to\pi/2^+}\tan x\]

Answer 14

E asks is the limit approaching from the right of pi/2

Answer 15

Yeah exactly unkle, we got the vertical asymptote at 3pi/2, So as x approaches pi/2, with asymptote at 3pi/2 you will get -infinity because its at the left side of the asymtotes

Answer 16

Picture

Answer 17

so i just ned to put a negative sign infront of my answer

Answer 18

Yes

Answer 19

thanks @.Sam. and @UnkleRhaukus , @Euler271
