Limits by Conjugates

The video tutorial introduces the concept of conjugates in solving limits, particularly when dealing with square roots. It explains how to find conjugates for expressions and demonstrates their usefulness in simplifying complex limit problems. The tutorial also introduces the concept of 'fancy one,' which involves multiplying by a form of one to maintain the value of an expression. Through examples, the video illustrates how to apply these concepts to solve limits effectively.

How do you determine which conjugate to multiply by when solving limits?

What is the conjugate of the expression 3 - sqrt(X)?

Explain the significance of canceling terms in limit problems.

What is the final result of the limit as X approaches 3 for the function (9 - X) / (3 - sqrt(X))?
