To find the derivative of the function sin(3x5), we will use the chain rule. The chain rule states that the derivative of a composite function f(g(x)) is f'(g(x)) * g'(x).
In our case, let:
- u = 3x5
- f(u) = sin(u)
Now, we need to find the derivatives of f(u) and u:
- f'(u) = cos(u)
- u’ = 15x4 (using the power rule)
Now, we can apply the chain rule:
Therefore, the derivative of sin(3x5) is:
cos(3x5) * 15x4
This simplifies to:
15x4 * cos(3x5)
In conclusion, the derivative of sin(3x5) is 15x4 * cos(3x5).
