3. Evaluate dr a. Start with the substitution ue and note that u2 =e2, This should lead to the integral du. b. Next use a trig. substitution u (You will end up with a sin 20. To convert back to u and then x you can use sin(20) 2 sin @ cos .) 3. Evaluate dr a. Start with the substitution ue and note that u2 =e2, This should lead to the integral du. b. Next use a trig. substitution...
