# Solving Integrals Using Substitution

The concept of solving integrals by substitution with trigonometric functions is modeled by a video designed for AP Calculus classes. The narrator works an example problem using substitution and shows that careful substitution makes evaluating integrals manageable.

##### Instructional Ideas

• Provide the class several opportunities to determine what can be used for substitution
• Have the class begin to find the integral using the methods they know before introducing substitution
##### Classroom Considerations

• Pupils should know how to integrate elementary functions
##### Pros

• The example shows how a complicated trigonometric function can be simplified through substitution
• The presenter highlights the portions he will substitute

• None
