WebAug 9, 2014 · p_1, p_2 = symbols ("p_1 p_2") p_1 = L.diff (phi_1.diff (t)) You created a symbol but then destroyed it by creating a Python variable with the same name, so when you try to differentiate wrt p_1 you are (as Aaron pointed out) differentiating wrt an expression, not a symbol that you created. Share. Improve this answer. Webe^x times 1. f' (x)= e^ x : this proves that the derivative (general slope formula) of f (x)= e^x is e^x, which is the function itself. In other words, for every point on the graph of f (x)=e^x, the slope of the tangent is equal to the y-value of tangent point. So if y= 2, slope will be 2. if y= 2.12345, slope will be 2.12345.

WebThe derivative of a function represents its a rate of change (or the slope at a point on the graph). What is the derivative of zero? The derivative of a constant is equal to zero, hence the derivative of zero is zero. What does the third derivative tell you? The third derivative is the rate at which the second derivative is changing.
