In this problem, we need to find the higher derivatives of the function, y is equal to 5x cube minus 2x squared.
00:11
Now, first of all, let us determine the first derivative.
00:16
The first derivative is d -y -d -x.
00:20
That is the derivative of 5x cube minus 2x squared.
00:23
So that will be 5 times the derivative of x -cube, which is 3x -square, minus 2 times the derivative of x square, which is 2x.
00:32
So this will be equal to 15x square minus 4x.
00:36
Next, let us determine the second derivative.
00:40
The second derivative is the derivative of 15x square minus 14x.
00:46
So that will be equal to 15 times the derivative of x square, which is 2x, minus 4 times the derivative of x, which is 1.
00:53
So this is equal to 30x minus 4.
00:59
Next, let us find the third derivative.
01:03
The third derivative will be the derivative of 30x minus 4 and that will be equal to 30 times 1 minus 0...
