h. In my blog I was attempting to find the IRC of GDP in 1940. I found the IRC by estimating
the tangent line to point (1940, 1.27) and selecting a point from that line
(1980, 4) and calculating the slope of the line. The slope of the tangent line
is equal to the instantaneous rate of change at our original point.
Your blog was clear and well articulated. It is fascinating to know that the US GDP is increasing $682.5 billion dollars a year.
ReplyDeleteyou explained the average rate of change clearly and your finding that the more further the point is from the year 1930 the greater the average rate of change, which indicated that the GDP increases faster than a linear line, and as the years go by the GDP gets greater and greater, which is clear by the results that you got from calculating the average rate of change.
ReplyDeletewell written, very clear and organized, and you fully explained everything that was required for this blog... Well done!
ReplyDeleteIt is very clear and organized work. you explained everything and well done .
ReplyDeleteI liked that you chose GDP as your topic! Very clear and well executed.

ReplyDeletevirginia,
ReplyDeletei enjoyed reading your post, and your graphs and tables are well organized and clear.
there is a bit of an issue with some of your results and calculations, though. in the beginning, you state that you want to find the IRC of the GDP in 1940, but your secant calculations are for 1930, making it kind of impossible for you to compare your tangent line (IRC) value from 1940. all of the calculations should have focused on the same year, so your this creates some error in your results. your separate explanations of the IRC and the secant lines are done well, even if they are not entirely related. let me know if you don't understand the error in your calculations.
good job. =]
