Question

( int e^{2 x} )
( lim _{x rightarrow pi / 4} frac{int_{2} f(t) d t}{x^{2}-i 4 / 16} )
Lt ( frac{0}{0} ) form ( 1^{circ} ) we well
( a beta / x y )
L Hosput Aule
( lim _{x rightarrow pi / 4} frac{f(t)}{2 x} )
( Rightarrow frac{left.f(x)_{r}right)}{2 x pi_{*}}=frac{2}{pi} fleft(frac{pi}{r}right) )

# sec?x 5 f(t) dt 11. lim x →0/4 X 2 equals
