• Trig sub 1: Basics and $\int \frac{1}{\sqrt{36-x^2}}dx$ and $\int \frac{x}{36+x^2}dx$ and $\int \frac{1}{\sqrt{x^2-36}}dx$
• Trig sub 2: $\int \frac{dx}{(1+x^2{)}^{5/2}}$
• Trig sub 3: $\int \frac{x^2}{\sqrt{1-4x^2}}dx$
• Trig sub 4: $\int \sqrt{e^{2x}-1}dx$
• Trig sub 5: $\int \frac{\sqrt{4-36x^2}}{x^2}dx$
