Insight number 2: to evaluate the limit of a:
1. Rational function: you can factorize and cancel out what you can
2. Radicals (subtractions of square roots): multiply and divide by the
conjugate. For example:
x² +1-x
x² +1-x²
V x2 + 1 - x=
VX2 + 1 + x
V.x2 +1 + x
1
VX2 + 1 + x
(V x2 +1 + x) =
=
= 1
x
3. Trigonometric functions: try to connect your limit with important
sin (x)
trigonometric limits like limx-0
If you are stuck with a trig limit, express all the trig functions in terms
of sine and cosine.
4. If you are composing continuous functions, you can pass the limit
inside the external function: lim -a f(g(x)) = f(lim,-a 9(x))

Step-by-step explanation:
P(Hugo is on time for a given class)=71%=0.71
If there are 57 classes during the semester
The number of times Hugo is on time to class during the semester will
=0.71 X 57
=40.47
Hugo is on time to class approximately 40 out of 57 times.
