Find the limits using L'Hospital's rule is possible:

lim (sin pix)/(x^2-16)
x->4

1/2

Step-by-step explanation:

if we put x=4 we get an undetermined limit that is 0/0 so we differentiate the numerator and denominator separately

then we insert the limit x=4 we get

so we get the

final answer is

so that would be the limit.

for future students the answer is b
