Q & A

What is the focus of the transcript?

The transcript focuses on the comparison of trigonometric functions in right triangles.

What is a right triangle?

A right triangle is a type of triangle that has one angle measuring 90 degrees.

What are the basic trigonometric functions used in right triangles?

The basic trigonometric functions in right triangles are sine (sin), cosine (cos), and tangent (tan).

How is sine defined in a right triangle?

Sine (sin) is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse.

What does the cosine function represent in a right triangle?

Cosine (cos) is the ratio of the length of the adjacent side to the hypotenuse in a right triangle.

What is the definition of tangent in a right triangle?

Tangent (tan) is the ratio of the length of the opposite side to the adjacent side in a right triangle.

How are these trigonometric functions applied in solving problems with right triangles?

These functions are used to find missing sides or angles in right triangles when certain information is given.

Can the Pythagorean theorem be used alongside trigonometric functions?

Yes, the Pythagorean theorem can be used to find missing side lengths, which can then be used with trigonometric functions to find angles or other sides.

What is the importance of knowing the angle when using trigonometric functions?

The angle is crucial because the trigonometric functions depend on the specific angle, affecting the ratio between the sides of the triangle.

How can trigonometric functions be used to determine the height of an object?

By measuring the distance to the object and the angle of elevation, trigonometric functions like sine or tangent can be used to calculate the object's height.
