What is a cosine?
In trigonometry, when we look at right triangles, the cosine is the ratio of the length of the adjacent side to the length of the hypotenuse.
How do you solve right triangles in Trigonometry?
you use the the 3 trigonometry functions , sin=opposite divided by hypotenuse cos=adjacent divided by hypotenuse tan=opposite divided by adjacent these are used to work out angles and side lengths in right angle triangles only!!! sine,cosine,tangent :)
What is soh cah toa in trigonometry?
SoH: used for finding the sine of a triangle in trigonometry: Opposite/HypotenuseCaH: used for finding the cosine of a triangle in trigonometry: Adjacent/HypotenuseToA: used for finding the tangent of a triangle in trigonometry: Opposite/Adjacent
What is trigonometry's circular function?
The basic circular functions are sine, cosine and tangent. Then there are their reciprocals and inverses.
What is the difference between trigonometry and geometry?
Trigonometry is specificly the study of a right triangle. For example, what is the cosine? Geometry is the study on shapes.
What are the angles of a triangle that has sides of 5.4cm by 7.1cm by 8.3cm?
Using the cosine rule in trigonometry the angles work out as 40.11 degrees, 57.9 degrees and 81.99 degrees
Is a cosine a trigonometry?
yes
