Find the derivative. t4 d [4 U3 du dt 0 a. by evaluating the integral and differentiating the result. b. by differentiating the integral directly. a. Evaluate the definite integral. d d 2+ 10 dt du = dt 5 0 (Simplify your answer. Use integers or fractions for any numbers in the expression.) Find the derivative of the evaluated integral. 4 du = 4+9 dt (Simplify your answer. Use integers or fractions for any numbers in the expression.)b. Which of the following is the correct way to find the derivative of the given integral directly? O A. The function cannnot be differentiated using the Fundamental Theorem of Calculus. O B. Substitute t" for u in the function in the integrand, then multiply by t. O C. Substitute t# for u in the function in the integrand. O D. Substitute t* for u in the function in the integrand, then multiply by the derivative of t* Therefore, 3 du = dt 0 (Simplify your answer. Use integers or fractions for any numbers in the expression.)
