WebJan 31, 2024 · yval_dash = [5, 16, 33, 56, 85] numpyDiff = [10. 24. 44. 70.] To calculate the numerical derivative you should do a "Difference quotient" which is an approximation of a derivative. numpyDiff = np.diff (yval)/np.diff (xval) The approximation becomes better and better if the values of the points are more dense. WebPlugging in your point (1, 1) tells us that a+b+c=1. You also say it touches the point (3, 3), which tells us 9a+3b+c=3. Subtract the first from the second to obtain 8a+2b=2, or 4a+b=1. The derivative of your parabola is 2ax+b. When x=3, this expression is 7, since the derivative gives the slope of the tangent. So 6a+b=7. So we have 6a+b=7 4a+b=1 WebMar 26, 2016 · Here’s the calculus. You write. Take the power and put it in front of the coefficient. Multiply.
