Solve the quadratic equation

The video tutorial explains how to solve trigonometric equations by factoring. It begins with moving all variables to one side and factoring common terms. The focus is on factoring sine squared of Theta into a product and solving the resulting equations. The tutorial then uses the unit circle to find angle solutions, specifically at 0, π/2, and π radians.

What is the first step in solving an equation by factoring?

• Add all variables to one side

• Multiply all terms by zero

• Divide by the highest coefficient

• Subtract constants from both sides

When factoring sine squared of Theta, what common factor is identified?

• Sine of Theta

• Cosine of Theta

• Tangent of Theta

• Theta itself

What equation is formed after factoring sine squared of Theta?

• Sine of Theta equals one

• Sine of Theta times Sine of Theta minus one equals zero

• Cosine of Theta equals zero

• Tangent of Theta equals one

How is the angle π related to the unit circle?

• It is half of a full circle

• It is three-quarters of a circle

• It is a full circle

• It represents a quarter turn

Which of the following is a solution for sine of Theta equals zero on the unit circle?

• 0

• 3π/2

• π/2

• π/4
