curvefit in python

OBJECTIVE: To conduct a frequency analysis on a rotating shaft, apply a bearing fixture on the stepped face of the rod at the two ends and find out the critical frequencies. INTRODUCTION-Resonance frequency of a system is the natural frequency of vibration / cyclic motion of a system or structure. Resonance is the…

OBJECTIVE-  To determinethe minimum cushion pressure needed to break a given thickness of iceusing an air cushion vehicle, Muller (“Ice Breaking with an Air Cushion Vehicle”) inMathematical Modeling: Classroom Notes in Applied Mathematics, SIAM 1987) derivedthe equation where p denotes the cushion pressure,…

  1.pcov is a 2d array with the estimated covariance of the parameters in popt. It canbe used to calculate the the standard deviation errors of popt. 2.popt gives the output of the coefficients that are obtained after calculation by the function curve_fit. 3.*popt refers to the values of coefficeints…
