Q & A

What is the main focus of the video?

The main focus of the video is to explain the trigonometric ratios in the context of a right triangle.

Which trigonometric functions are mentioned in the video?

The video mentions sine, cosine, tangent, secant, cosecant, and cotangent.

What does the acronym SOHCAHTOA represent?

SOHCAHTOA is a mnemonic for remembering the trigonometric ratios: Sine is Opposite over Hypotenuse, Cosine is Adjacent over Hypotenuse, and Tangent is Opposite over Adjacent.

How is sine of an angle defined in the video?

Sine of an angle is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse in a right triangle.

What is the definition of cosine given in the video?

Cosine is defined as the ratio of the length of the adjacent side to the length of the hypotenuse in a right triangle.

How is tangent of an angle explained in the video?

Tangent of an angle is explained as the ratio of the length of the side opposite the angle to the length of the adjacent side.

What is the reciprocal relationship between sine and cosine mentioned in the video?

The reciprocal relationship mentioned is that cosine is the reciprocal of sine, and vice versa, which means that if sine is the opposite over hypotenuse, then cosine is the adjacent over hypotenuse.

What is the relationship between tangent and cotangent as explained in the video?

The video explains that tangent and cotangent are reciprocal functions, meaning that if tangent is opposite over adjacent, then cotangent is adjacent over opposite.

What is the significance of the right triangle in trigonometry as discussed in the video?

The right triangle is significant in trigonometry because it provides a foundation for defining the trigonometric ratios using the lengths of its sides relative to one of its angles.

How does the video use the example of a right triangle to explain the trigonometric ratios?

The video uses an example of a right triangle where it assigns specific lengths to the sides relative to an angle, and then calculates the sine, cosine, and tangent of that angle using these lengths.

What is the mnemonic used in the video to remember the reciprocal trigonometric ratios?

The mnemonic used in the video to remember the reciprocal trigonometric ratios is 'SOHCAHTOA', which stands for Sine is Opposite over Hypotenuse, Cosine is Adjacent over Hypotenuse, and Tangent is Opposite over Adjacent.
