Simplify trigonometric expression by multiplying rational expressions

The video tutorial explains how to handle fractions inside parentheses, emphasizing the importance of distributing the fraction to each term when separated by multiplication or division. It highlights that this method does not apply to addition or subtraction. The tutorial then demonstrates simplifying a trigonometric expression by canceling terms and applying power rules, resulting in a simplified expression of 1/4 cosine of X.

What must be ensured when distributing a fraction inside parentheses?

• The fraction is only applied to terms separated by addition.

• The fraction is applied to every term not separated by addition or subtraction.

• The fraction is only applied to terms separated by subtraction.

• The fraction is applied to every term, regardless of operation.

When multiplying trigonometric functions, what is crucial to remember?
