What is the value of the sine ratio?

The sine ratio is equal to the length of the side opposite the angle divided by the length of the hypotenuse.

What is the value of the cosine ratio?

The cosine ratio is equal to the length of the adjacent side divided by the length of the hypotenuse.

What is the value of the tangent ratio?

The tangent ratio is equal to the length of the opposite side divided by the length of the adjacent side.

Why are these ratios important in trigonometry?

These ratios are important because they help us solve for unknown sides and angles in right triangles, and they are fundamental to many mathematical and scientific calculations.

How can I remember the order of the reciprocal trigonometric ratios?

A common mnemonic device for remembering the order of the ratios is SOH (sine is opposite over hypotenuse), CAH (cosine is adjacent over hypotenuse), and TOA (tangent is opposite over adjacent).
