WebOct 11, 2014 · If I take the first derivative and set it equal to 0.0 I get the extrema of that function. I'm not interested in a numerical result, I want an expresion involving time and the rest of the parameters in my equations. Solve[] gives Solve::nsmet: This system cannot be solved with the methods available to Solve. WebRecall that the definition of the derivative at some point x is the limit as h approaches 0 of (f(x+h)-f(x))/h. Substitute the x in f(x) with x+h and evaluate f(x) at this point. By plugging this value into the definition of the derivative and simplifying, you will find a new expression.

WebSo when we differentiate a constant we find that value is 0. Hence: f (x) = k will be f' (x) = 0 when differentiate, assuming k is an arbitrary constant (meaning it can be any constant you want, 2, 5, 84385, whatever, they all have the same slope of 0). Which is 0/h, and hence the difference quotient is 0, the slope is 0. WebDifferential equations relate a function to its derivative. That means the solution set is one or more functions, not a value or set of values. Lots of phenomena change based on …
