Sine cosine and tangent calculator
Notes on Find That Side or Angle Learning Task
Graphing calculators include keys to give values for the sine, cosine, and tangent functions that are very accurate approximations for all trigonometric ratios of degree measures greater than 0° and less than 90°. You should use calculator values for trigonometric functions, as needed, for the remainder of this task.

To solve the problem, write an equation using tangent, use the Gizmo to find the tangent value you need, and solve for the unknown height. Show your work below. Height of the tree: Challenge: Tangent may be defined as the ratio of the sine to the cosine: tan(θ) = . Use algebra to show that this is equivalent to tan(θ) = . Show your work.

In other words, the tangent, cosine, or sine of an angle will always stay the same, no matter what the side lengths are. The only criteria is if the triangles are similar, or right triangles in this instance. Knowing this relationship also leads to important problem-solving techniques. For example, students can find any side of a right triangle ...

Ask students to use a calculator to find the sine, cosine, and tangent of pairs of complementary acute angles, angle A and angle B. In a class discussion, ask students what observations they can make about the trigonometric ratios. Lead students to discover that the sines and cosines of complementary angles are equal to one another.

Exploring Sine and Cosine Graphs Learning Task. In the previous task you used your calculator to model periodic data using a sine graph. Now you will explore the sine, cosine, and tangent graphs to determine the specific characteristics of these graphs. Using your knowledge of the unit circle, complete the following chart for f(x)=sin x.

For Example 1, compute the sine, cosine, and tangent of the indicated angle. For the triangle in Example 1, compute the tangent of both the non-right angles, and then use the inverse tangent function to find both angles. Check your work by finding the sum of those two angles. (What should it be?) In Example 3, find the length of side y.
