Learn how to find all the solutions to a trigonometric equation

The video tutorial explains how to solve trigonometric equations using the unit circle. It covers finding solutions by adding multiples of 2π and explores simplifying these solutions using reference angles and π. The tutorial emphasizes the importance of simplifying answers for clarity and understanding, akin to simplifying fractions.

What is the general form of the solution for the equation 4 cosine squared of Theta equals 3/4?

• Theta equals π/6 + 2πN

• Theta equals π/4 + 2πN

• Theta equals π/3 + 2πN

• Theta equals π/2 + 2πN

How can you find additional solutions for an angle with a reference angle of π/6?

• By adding π/3

• By adding π/2

• By adding π

• By adding 2π

What is the simplified form of the solution for angles with a reference angle of π/6?

• π/4 + πN

• π/6 + πN

• π/3 + πN

• π/2 + πN

Why is it important to simplify trigonometric solutions?
