• A) \(\frac { 1 } { 8 } \left( \ln \left| 4 + 5 \sin ( x ) + 4 \sin ^ { 2 } ( x ) \right| - \frac { 10 } { \sqrt { 39 } } \arctan \left( \frac { 8 \sin ( x ) + 5 } { \sqrt { 39 } } \right) \right) + C\)
• B) \(\frac { 2 } { \sqrt { 39 } } \arctan \left( \frac { 8 \cos ( x ) + 5 } { \sqrt { 39 } } \right) + C\)
• C) \(\frac { 1 } { \sqrt { 39 } } \ln \left| \frac { 8 \sin ( x ) + 5 - \sqrt { 39 } } { 8 \sin ( x ) + 5 + \sqrt { 39 } } \right| + C\)
• D) \(\frac { 2 } { \sqrt { 39 } } \arctan \left( \frac { 8 \sin ( x ) + 5 } { \sqrt { 39 } } \right) + C\)
• E)\(\frac { 1 } { \sqrt { 39 } } \ln \left| \frac { 8 \cos ( x ) + 5 - \sqrt { 39 } } { 8 \cos ( x ) + 5 + \sqrt { 39 } } \right| + C\)

To Choke

To experience difficulty breathing because of a constricted or obstructed throat or lack of air.

Sinoatrial Node

The heart's natural pacemaker, a small, specialized cluster of cells located in the right atrium that regulates the heart’s electrical impulses and hence its beating.

Atrioventricular Node

A part of the cardiac conduction system that controls the heart rate by delaying the transmission of electrical impulses from the atria to the ventricles.

Bundle of His

A collection of heart muscle cells specialized for electrical conduction that transmits the electrical impulses from the AV node to the ventricles of the heart.
