SOH-CAH-TOA. Image mnemonic to help remember the ratios of sides of a right triangle. The sine, cosine, and tangent ratios in a right triangle can be remembered by ...
For instance, a mnemonic is SOH-CAH-TOA: [34] Sine = Opposite ÷ Hypotenuse Cosine = Adjacent ÷ Hypotenuse Tangent = Opposite ÷ Adjacent. One way to remember the letters is to sound them out phonetically (i.e. / ˌ s oʊ k ə ˈ t oʊ ə / SOH-kə-TOH-ə, similar to Krakatoa). [35]
COS (54D: The "C" in "SOH-CAH-TOA") SOH-CAH-TOA is a mnemonic used in trigonometry to remember how to calculate the sine, cosine (COS), and tangent of an angle of a right triangle.
The mnemonic "SOHCAHTOA" (occasionally spelt "SOH CAH TOA") is often used to remember the basic trigonometric functions: [36] Sine = Opposite / Hypotenuse; Cosine = Adjacent / Hypotenuse; Tangent = Opposite / Adjacent; Other mnemonics that have been used for this include: Some Old Hippie Caught Another Hippie Tripping On Acid.
In mathematics, sine and cosine are trigonometric functions of an angle.The sine and cosine of an acute angle are defined in the context of a right triangle: for the specified angle, its sine is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse), and the cosine is the ratio of the length of the adjacent leg to that ...
Used since the 1950s to make consumer products nonstick, oil- and water-repellent, and resistant to temperature change, PFAS chemicals have been linked to serious health problems, including cancer ...
In October 2021, a video went viral the footage displayed showed the math teacher Candice Reed [3] at John W. North High School in Riverside Unified School District wearing a fake feather headdress while dancing around the classroom and chanting "SOH-CAH-TOA", which is a mnemonic for remembering a trigonometry principle. [4] She was suspended.
