Find the integral using an appropriate trigonometric substitution. 
Definitions:
Antigravitational Fields
Antigravitational fields are theoretical fields that would counteract the force of gravity, allowing objects to float or fly without conventional propulsion or support, primarily a concept in speculative physics and science fiction.
Fusion Reactors
Devices designed to generate energy by fusing atomic nuclei together, a process similar to what happens in the sun.
Additive Manufacturing
A process of creating three-dimensional objects by adding layer upon layer of material, commonly referred to as 3D printing.
Economies of Scale
The cost advantages that enterprises obtain due to their scale of operation, resulting in cost per unit of output decreasing with increasing scale.
