Trigonometry Math facts:
What is sine used for in trigonometry
Use sine ratio to calculate angles and sides (Sin = h o )
One of the trigonometric ratios is the sine ratio. It is the opposite side over the hypotenuse of right triangles. In other words, we can find the angles and sides of right-angled triangles by using the sine ratios.
What is sin cos tan?
Sin is equal to the side opposite the angle that you are conducting the functions on over the hypotenuse which is the longest side in the triangle. Cos is adjacent over the hypotenuse. And tan is opposite over adjacent, which means tan is sin/cos. This can be proved with some basic algebra.
Why SIne is called sine
The word "sine" (Latin "sinus") comes from a Latin mistranslation by Robert of Chester of the Arabic jib, which is a transliteration of the Sanskrit word for half the chord,
Names of triangles:
"There are four types of triangle: equilateral, isosceles, scalene, and right-angled." Fleur said: "There are only three types of triangle. These are equilateral, isosceles and scalene.

Hello Zion,
ReplyDeleteI like how you explained what sin, cos and tan is. You have a lot of useful information on here and it is helpful for me and for others. Maybe next time you could add a picture.

Hey Zion, Good job on putting time and effort in to making this bog post about Pythagoras Therum, it very much helped me understand more about how to use Soh cah toa. In the future maybe add like 1 or 2 pictures to make it look outstanding. Great Job though Zin
ReplyDeleteHey, nice work. Very nicely layed out and clear information.
