Dive into calculus problems on limits, continuity, and discontinuity. Practice finding limits, identifying discontinuities, writing piecewise functions, and finding tangent and normal lines.

Calculus Gang Get in groups of three. Hopefully these problems will not take you to the limit of learning.
#1 • Find the limit If it exists
#2 • Find the limit.
#3 Give any points (x) where f(x) is not continuous and tell what type of discontinuity exists at that point.
#4 • Write a piecewise function that would remove the discontinuity.
#5 • Find the equation of the tangent line (if it exists) at x=3
#6 • Find the equation of the normal line at x=1 for
Answers • 1) 7 • 2) positive infinity • 3) x=5; point discontinuity; x=-5 jump discontinuity • 4) • 5) Does not exist; left and right hand derivative do not match. • 6) y-6=-1/2(x-1)
