Today we went to the computer lab to work on the Logarithmic scale, semilog graphs, exponential eguations and more which I did not get to.
THE LOGARITHMIC SCALE
- It is not possible to have a negative or zero y-coordinate on a logarithmic scale because [tag]logarithms[/tag] are exponents and no exponent can get 0 or negative numbers. Anyhing to the 0 power is one and anytihng to the negative power is less than 1 but greater than 0.
- The relationshipship between the y coordinates of the point A and its dialation is the y-coordinate is squared 10^2 * 10^2 = 10^4.
- The points on the logarithmic scale are related by multiplying the power numbers.
In conclusion from this section we learned that adding the lengths is the same as multiplying the power numbers. This was a review of what Mr. B told us yesterday.
SEMILOG GRAPHS
Semilog graphs are different. The x axis shows the exponent numbers and the y axis displays the powers(10^1,10^2,…). The intervals on the y axis are uneven because of ratios. This makes a parameter of x=1 and y=2v(both increasing at the same rate) a concave downlow sloped graph.
EXPONENTIAL EQUATIONS
Exponential equations on semigraghs from a straight linear shape. This is because of the y axises powers and the intervals in the graph.
This is as far as I get and I don’t fully understand. And I am not positive it is all correct, but I am pretty sure it is. Hope it helped you a little.
The next scribe will be Shelby.
