My Class Experience

I had a both challenging and great experience in this class. Challenging because there were times when the class materials were tough and overwhelming; and great because actually learning the material and managing to do well helped me realize that I can do whatever I put my mind to. Also, algebra and trigonometry is math that I can use throughout both my life and future career as a nurse. In addition, we had a Professor that was there to assist us with any questions and concerns we may have had, and gave us many opportunities to increase our grade.

Parabola Equation

A satellite has a parabolic dish with a diameter of -1 cm. The radio signals are reflected on a focal point, being the focus of the parabola. If the focal length is 1.4 cm, find the depth of the dish.

 

Real World Parabola

The satellite dish above can be considered reflective properties of parabolas. The signals that are received are directly sent to the focus, which are then correctly reflected to a receiver (signals are sent out parallel to the axis). These signals are then interpreted and are transmitted as channels on our TV. The same principle applies to radio frequencies too. Parabolic mirrors and heaters also work on the same principle.
