Do you know what the trigonometric function is? It is a math thingy that you should learn when you are studying middle school 3-2 math. It is made of basically, 3 functions; which is the sine(sin), cosine(cos) and tangent(tan). These 3 functions are the basics of the trigonometric function. But, first let's know about the definition of the trigonometric function. The trigonometric function is the ratio between the smaller angle and the two bigger angles. Now, lets go to the basics. First, there is a reciprocal function with the sine and cosine and tangent function. It is the cosecant(csc), secant(sec), and the cotangent(cot). Sine is R divided by Y, cosine is R divided by X, and tangent is X divided by Y. And the cosecant, secant , and the cosecant is sine divided by 1, secant is cosine divided by 1 and cotangent is tangent divided by 1. You can easily memorize this thingy by listening to the trigonometric function song. Here is the link; https://www.youtube.com/watch?v=bTs0DcMxDT8.
You can use this song to just listen, or you can use this song to really memorize the trigonometric function. By the way, I used this song to memorize the trigonometric function. :)
