Learn how to verify a trigonometric identiy using pythagorean identities

The video tutorial explains how to simplify a trigonometric expression involving sine and cosine. The teacher guides through choosing sides, applying operations, and using the Pythagorean identity to simplify the expression. The process involves finding a common denominator, rewriting expressions, and factoring to reach the final simplified form.

Why is it easier to make the right side of the equation look like the left side?

• Because the left side has fewer terms

• Because the right side has fewer terms

• Because the left side is more complex

• Because the right side is more complex

What is the common denominator used in the expression?

• sine of Theta

• cosine of Theta

• 1 minus cosine of Theta

• 1

Which identity is used to rewrite sine squared of Theta?

• Sine squared Theta equals cosine Theta

• Sine squared Theta equals one

• Sine squared Theta plus cosine squared Theta equals one

• Sine squared Theta equals cosine squared Theta

What happens to the terms 1 minus cosine of Theta in the final step?

• They are subtracted

• They are divided out

• They are multiplied

• They are added together

What is the final simplified expression?

• Secant of Theta

• Tangent of Theta

• Cosine of Theta

• Sine of Theta
