Still stuck...see post at 3:34pm. I don't think I'm understanding the instructions regarding what #'s to use for sin and cos.
I apologize for the confusion you're experiencing. To help you understand the instructions regarding what numbers to use for sine (sin) and cosine (cos), let's break it down.
Sine (sin) and cosine (cos) are trigonometric functions used to relate the angles in a right triangle to the lengths of its sides. In order to use these functions, you need to identify the angle you are working with.
Here's the step-by-step process:
1. Identify the angle: Determine which angle (in degrees or radians) you are working with. The angle is usually denoted with a Greek letter such as θ (theta).
2. Choose the appropriate trigonometric function: If you need to find the ratio of the length of the opposite side to the hypotenuse, use sine (sin). If you need to find the ratio of the length of the adjacent side to the hypotenuse, use cosine (cos).
3. Determine the values: Now, you need to find the lengths of the sides of the right triangle. The side opposite the angle is called the opposite side, the side adjacent to the angle is called the adjacent side, and the longest side (opposite the right angle) is called the hypotenuse.
4. Calculate the trigonometric value: Divide the length of the specific side (opposite or adjacent) by the length of the hypotenuse. The result will be the value of either sin or cos.
For example, if you have an angle of 30 degrees and you need to calculate sin(30), you would divide the length of the side opposite the angle by the length of the hypotenuse.
If you can provide more specific details about the problem or the instructions you are following, I can give you a more tailored explanation.
