Answer:
by L'Hospital rule, which states that: when you get an indeterminate form after assuming that
lim
x
→
c
f
(
x
)
=
f
(
c
)
, then
lim
x
→
c
g
(
x
)
h
(
x
)
=
g
'
(
c
)
h
'
(
c
)
⇒
lim
x
→
π
4
(
sec
x
)
2
+
(
csc
x
)
2
1
placing values of
x
=
π
4
=
(
√
2
)
2
+
(
√
2
)
2
1
=
4
1
=
4
you can find the value of the limit as now it is not in the indertiminate form
hope you find it helpful :)
