A memory trick that I learned for trigonometric values is:

Sin: opp/hyp

Cos: adj/hyp

tan: opp/adj

What does socotoa mean?

It is an 'Aide memoire' to help with using the correct sides , with the correct function. . socatoa, becomes SOHCAHTOA ; SOH , CAH, TOA. SOH is Sin(angle) = Opposite/Hypotenuse. CAH is Cosine(Cos(angle)) = Adjacent/ Hypotenuse TOA is Tangent(Tan(Angle)) = Opposite / Adjacent.


How do you do sine and cosine?

It would help if I knew a little more information about what you're looking for, in order to better answer your question, but here are the basics.For a right triangle, given one of the angles that is not the 90° angle:sine is the ratio of the length of the side opposite the angle divided by the length of the hypotenuse.cosine is the ratio of the length of the side adjacent to the angle divided by the length of the hypotenuse.One way to remember this is: Sine, Cosine, Tangent; then think of Old Harry Always Has Old Apples. Sine = O/H, Cosine = A/H, and Tangent = O/A,where O is the Opposite side, A is the Adjacent side, and H = Hypotenuse.Another one that somebody taught me is: Oh Heck Another Hour Of Algebra. Pick whatever helps you to remember.


In a right triangle the ratio of adjacent side to hypotenuse?

Ah, what a lovely question we have here. In a right triangle, the ratio of the adjacent side to the hypotenuse is called cosine. It helps us understand the relationship between the lengths of the sides and the angles of the triangle. Just remember, happy little ratios like these can help you create beautiful mathematical landscapes on your canvas of knowledge.


How does geometric properties help you find the value of trigonometric functions?

Geometric properties, particularly those related to right triangles and the unit circle, provide a visual framework for understanding trigonometric functions. In a right triangle, the ratios of the lengths of the sides (opposite, adjacent, and hypotenuse) directly define sine, cosine, and tangent. Similarly, on the unit circle, the coordinates of points correspond to the values of these functions for different angles, allowing for easy calculation of sine and cosine values. Thus, geometric insights simplify the evaluation and interpretation of trigonometric functions.


Where to use sine and cosine in physics?

Sine and cosine functions are used in physics to describe periodic phenomena, such as simple harmonic motion, sound waves, and alternating currents in circuits. They help in modeling phenomena that exhibit oscillatory behavior over time or space. Sine and cosine functions are also used in vector analysis to analyze the components of vectors in different directions.


How do you find the sin of a triangle?

Sin is opposite over hypotenuse. Just think of this to help you: SOH-CAH-TOA Sine = opposite over hypotenuse Cosine = adjacent over hypotenuse Tangent = opposite over adjacent Hope that helps you.

What is the square-root of a tangent?

The tangent is essentially the derivative of the function. The square-root is just what ever function that is takes two of that function to equal the tangent. If you need further help on this question just send me a message on my message board and id be glad to help you out.
