Asecond order differential equation for the function yt o a differential equation involving the second power of y a differential equation involving the second derivative of y at least two terms involving y o a differential equation involving the square of the first derivative of y

Hi! A second order differential equation for the function y(t) has the next shape:

Where p(t), q(t) and g(t) are functions of t.

Then a second order differential equation for y is a differential equation involving the second derivative of y.

Is useful to remember that the order in a differential equation tells us the number of derivations involved in our function, for example, a "third order differential equation" is that involving the third derivative of y, but usually for orders above of two, are called "higher orders differential equations"

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
