When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- Two corners of a triangle have angles of #(3 pi ) / 8 # and # pi / 3 #. If one side of the triangle has a length of #2 #, what is the longest possible perimeter of the triangle?
- Two corners of a triangle have angles of # (7 pi )/ 12 # and # pi / 8 #. If one side of the triangle has a length of # 12 #, what is the longest possible perimeter of the triangle?
- A cone has a height of #5 cm# and its base has a radius of #4 cm#. If the cone is horizontally cut into two segments #2 cm# from the base, what would the surface area of the bottom segment be?
- A circle has a radius of #6x^9y^5#. The area of a circle can be found using A = Pi(radius)^2. What is the area of this circle in square centimeters?
- A pyramid has a parallelogram shaped base and a peak directly above its center. Its base's sides have lengths of #7 # and #8 # and the pyramid's height is #5 #. If one of the base's corners has an angle of #pi/4#, what is the pyramid's surface area?
