Learn how to integrate u substitution with trig

The video tutorial covers U-substitution in trigonometry, focusing on integrating secant U times tangent U. It begins with an introduction to the concept, followed by defining U and DU. The integration process is explained step-by-step, and the tutorial concludes with tips for reviewing the material.

What is the first step in identifying a function for u-substitution?

• Integrating the entire expression

• Setting the derivative equal to zero

• Identifying a function within a function

• Finding the derivative of the outer function

When adjusting the differential, what is necessary if you have a negative sign?

• Add a positive constant

• Ignore the negative sign

• Multiply by zero

• Factor out the negative sign

What is the integral of secant U tangent U?

• Secant U

• Tangent U

• Cosine U

• Sine U

What is the derivative of secant Theta?

• Tangent Theta

• Sine Theta

• Cosine Theta
