Answer:
The second-order derivative is -9sin(3x-2).
Step-by-step explanation:
Given:
sin(3x-2)
To find:
Second-order derivative
Solution:
Let y = sin(3x-2)
Differentiating w.r.t x, we get
We know that the derivative of sin(x) is cos(x). Using this and applying the chain rule, we get
The derivative of x is 1 and that of a constant is 0. Therefore,
This is the first derivative of sin(3x-2) w.r.t x.
To find the second derivative, we again differentiate dy/dx w.r.t. x. Hence,
Substituting the obtained value of dy/dx, we get
The derivative of cos(x) is -sin(x). Using this and the chain rule, we get
Therefore, the second derivative of sin(3x-2) is -9sin(3x-2).
