The derivative of the function f is defined by f′(x)=(x2+3)sin(3x). If f(2)=7, then use a calculator to find the value of f(6) to the nearest thousandth.Answer:
Q. The derivative of the function f is defined by f′(x)=(x2+3)sin(3x). If f(2)=7, then use a calculator to find the value of f(6) to the nearest thousandth.Answer:
Integrate f′(x) from 2 to 6: To find f(6), we need to integrate f′(x) from 2 to 6 and add the result to f(2) since f(2)=7.
Set up integral: Set up the integral of f′(x) from 2 to 6.∫26(x2+3)sin(3x)dx
Evaluate integral numerically: This integral does not have an elementary antiderivative, so we will use a calculator to evaluate it numerically.Use a calculator to evaluate the integral.
Calculate numerical value: After calculating the integral on a calculator, we get a numerical value. Let's denote this value as I.I≈[Calculator Output]
Find f(6): Now, add the value of f(2) to the integral result to find f(6). f(6)=f(2)+I f(6)=7+I
Add f(2) to integral result: Replace I with the numerical value obtained from the calculator to find f(6).f(6)≈7+[Calculator Output]
Replace I with value: Round the result to the nearest thousandth as required by the question prompt.f(6)≈[Rounded Value]
