What connects a function and its derivatives?
What connects a function and its derivatives?
A differential equation connects a function and its derivatives.
What does a derivative show?
What does a derivative show?
A derivative shows how a function changes over time.
What is the purpose of integration?
What is the purpose of integration?
Integration finds the starting function from its derivative.
What is a solution in differential equations?
What is a solution in differential equations?
A solution is a function that fits the differential equation.
What type of derivatives does a first-order equation have?

What is the general form of first-order equations?
What is the general form of first-order equations?
The general form is y'(t) = f(t, y(t)).
What type of solutions do differential equations have?
What type of solutions do differential equations have?
