Q. The derivative of the function f is defined by f′(x)=x2cos(2x+3). If f(0)=4, then use a calculator to find the value of f(6) to the nearest thousandth.Answer:
Set up integral: To find f(6), we need to integrate the derivative f′(x) from 0 to 6 and then add the initial value f(0) to the result of the integration.
Evaluate integral: First, we set up the integral of f′(x) from 0 to 6: ∫06x2cos(2x+3)dx
Add initial value: We use a calculator to evaluate the definite integral. This step involves numerical integration, which is typically not done by hand for functions like this one.
Calculate f(6): After calculating the integral on a calculator, we add the result to the initial value f(0)=4 to find f(6).
Report final value: Assuming the calculator gave us the correct value of the integral, we would then report the value of f(6) to the nearest thousandth.
