The following antiderivatives can be evaluated using u-substitution. Apply an appropriate u-substitution to find the antiderivative. (4z - 5) dz (a) (b) sin da 3. Evaluate the antiderivative using the following u-substitutions: (a) u = sin z (b) u = cos x 4. Evaluate the antiderivative Are your results the same? Discuss with your group and decide whether one of these results is correct and the other is wrong, or if both are correct. Back up your decision with some math! using the following u-substitutions: (a) u =tan(x) (b) u = sec(x) (c) 3) ft(1-13)1/ dt (d) tan(a) da sinr cos r dr fu tanz sec z dr Are your results the same? Discuss with your group and decide whether one of these results is correct and the other is wrong, or if both are correct. Back up your decision with some math!
