WebMay 7, 2024 · 1. Link. You CANNOT simply swap x and y, and fit a new polynomial to the result, thus model the curve as x (y). Think about what that would mean. When you swap x and y, you now have a relationship that has THREE values of x for most values of y. This is not a function. A polynomial is useless there. No polynomial exists that predicts three ...

With reference to the plot that I have, I managed to find the peak values (as denoted by the blue arrows) for each curve of the graph. Now I would like to find the x values (time) for 30% and 90% of the peak y value (torque) that I found.
WebAs your hint says, it is easy to solve your particular equation when y = 0 as you have. − 0.3 x 3 + 0.5 x 2 + 3.83 x = 0. so either x = 0 or − 0.3 x 2 + 0.5 x + 3.83 = 0 and you can solve the latter as a quadratic. It is usually not so easy when y ≠ 0 or in general for a cubic. Wikipedia gives the general (sometimes complex) form of the ...
