**Trigonometric Ratios Date Period Kuta Software LLC**

Demonstrates how to use trig ratios to do simple solving of triangles. Search . Return to the Lessons Index so "opposite" and "adjacent" can have very different values. This tells you that the tangent ratio, being (opposite) / (adjacent), can have very large and very small values, depending on the triangle.... Finding Trigonometric Ratios Date_____ Period____ Find the value of each trigonometric ratio to the nearest ten-thousandth. 1) tan A 16 34 30 A B C 2) cos C 12 9 15 C B

The ratio of the opposite to the adjacent is known as the tangent ratio or the tangent of the angle . (The name comes from an earlier time and involves the use of circles.)... The ratio called tangent (tan) of an acute angle in a right angled triangle is defined as the ration between the side opposite the angle and the side adjacent to the angle .

Lesson 8-4 Sine and Cosine Ratios 439 Sine and Cosine Ratios The tangent ratio, as you have seen, involves both legs of a right triangle.The sine and cosine ratios involve one leg and the hypotenuse. of &A = of &A = These equations can be abbreviated: sin A = cos A = Writing Sine and Cosine Ratios Use the triangle to write each ratio. a. sin T sin T == b. cos T cos T == c. sin G sin G == d... Specifically, they are the inverses of the sine, cosine, tangent, cotangent, secant, and cosecant functions, and are used to obtain an angle from any of the angle's trigonometric ratios. Inverse trigonometric functions are widely used in engineering, navigation, physics, and geometry Notation

## How To Write Tangent Ratios

### Once we were comfortable we moved into writing the ratio and finding the angle out. We also used this example to write the tangent ratio of the other angle. We also used this example to write the tangent ratio of the other angle.

- For example, in the figure above, the cosine of x is the side adjacent to x (labeled a), over the hypotenuse (labeled h): If a=12cm, and h=24cm, then cos x = 0.5 (12 over 24).
- Introduce terminology of sine, cosine, and tangent to define each ratio and as a convenient way of referencing the ratios. Students place these terms above the
- Whenever the ratio is found by using the opposite side and the hypotenuse, we call it sine ratio instead of tangent ratio. We then say that sine 45 degrees is equal to 0.707. In short, we can use the symbol sin instead of sine and write sin (45 degrees) = 0.707
- Start with the ratio identity involving sine, cosine, and tangent, and multiply each side by cosine to get the sine alone on the left. Replace cosine with its reciprocal function. Solve the Pythagorean identity tan 2 Î¸ + 1 = sec 2 Î¸ for secant.
