Hi , I have an assignment which requires that I draw tangents from the point of inflection on a peak to the x-axis.I still cannot figure out how to do that using qtiplot or excel.
Can't you just print out the plot of the curve, and then manually draw in the tangent line?selseg said:Hi , I have an assignment which requires that I draw tangents from the point of inflection on a peak to the x-axis.I still cannot figure out how to do that using qtiplot or excel.
I'm having a bit of a problem with the phrase "the point of inflection on a peak". Except for things like square waves, inflection points don't happen on peaks.selseg said:Hi , I have an assignment which requires that I draw tangents from the point of inflection on a peak to the x-axis.I still cannot figure out how to do that using qtiplot or excel.

Are you quoting the assignment precisely?
The point of inflection is where the curve changes from concave up to concave down or vice versa. This can be identified by finding the point where the slope of the curve is equal to zero or by looking for a change in the direction of the curve.
Yes, you can draw a tangent from any point of inflection on the chart. However, the tangent will only be perpendicular to the curve at the point of inflection and may not intersect with any peaks on the chart.
To draw a tangent from a point of inflection, first identify the point of inflection on the chart. Then, draw a line that is perpendicular to the curve at that point. This line will be the tangent to the curve at the point of inflection.
Drawing a tangent from a point of inflection can help us understand the behavior of the curve at that point. It can also provide information about the rate of change of the curve at the point of inflection.
Yes, there are some limitations to drawing tangents from points of inflection on a chart with peaks. The tangent may not intersect with any peaks on the chart, and it may not accurately represent the overall behavior of the curve at that point. Additionally, if the point of inflection is located at a sharp peak, it may be difficult to accurately draw a tangent at that point.
