2-In a paragraph or two, at least 100 words, what is an HDTV? Explain the meaning of HDTV. How is an HDTV different from previous ordinary televisions?
3-Derive a formula for the area of the screen of an HDTV as a function of only the height of the screen.
4-Derive a formula for the diagonal of the screen as a function of the height of the screen.
5-Derive a formula for the diagonal of the screen as a function of the area of the screen.
6-Illustrate with a graph the relationship between the diagonal and the area of the screen. Please make sure your graph is appropriately labeled.
7-What is the diagonal if the area is 2,823 cm^2?

========================
2-In a paragraph or two, at least 100 words, what is an HDTV? Explain the meaning of HDTV. How is an HDTV different from previous ordinary televisions?
You should do that.
=========================
3-Derive a formula for the area of the screen of an HDTV as a function of only the height of the screen.
Area = H*W
W = (16/9)*H
Area = 16h^2/9
===================
4-Derive a formula for the diagonal of the screen as a function of the height of the screen.
Do it like #3
==================
5-Derive a formula for the diagonal of the screen as a function of the area of the screen.
It's a right triangle.
====================
6-Illustrate with a graph the relationship between the diagonal and the area of the screen. Please make sure your graph is appropriately labeled.
Good idea.
===================
7-What is the diagonal if the area is 2,823 cm^2?
