So we know, for example, root3/2 and 1/2 is the coordinate at 30° using a 30, 60, 90 triangle. In that right triangle, however, the hypotenuse is 2 while the radius in our unit circle is 1. Can you help me understand? Is it just by proportion that our coordinates make sense? What am I missing?

Question, is the unit circle not much about solving but rather memorizing?

@ellaconsole8491 4 ай бұрын

yea its mainly just memorizing but the angles go in increments of 30 and 45 degrees so just remember the basic angles like 180, 270, 90, and 360/0 and then just go from there!

@mariadelmarcaparos2324 4 ай бұрын

Remember the base its still sin from x axis and the y axis is cosine ,but if u use on the number just switch for example the sin is on the first rownbecause always first is sin because its x ,but if u choose them (1/2, 2/3) sin here is in the second row which is 2/3 then the cosine which is Y axis u choose 1/2 which in reality that is for X value just switch the choice of number but in base axis they are still sin is x axis and the y is cosine axis .hope this can help

@mariadelmarcaparos2324 4 ай бұрын

Sin x axis always the second option of coordinates (y -value) Cosine y axis always at first option number (x-value)

hey chem tutor instead of memorizing is there another way to this if yes then please do let me know cuz its hard to memorize this by heart and if there was some fool proof way of doing this w/o memorizing i really would like to know

the x-coordinate of B is the cosine of the angle, and the y-coordinate of B is the sine of the angle.

If sin is the X-value and cos is the y-value, then what is tan?

@hoeman23 6 ай бұрын

Sin is the Y value. Cos is the X value. Tan is the y/x, or sin/cos

But there base as axis is still sin and cosine x is sin ,y is cosine but there base in number is opposite like switch@@hoeman23

When I put these into my calculator they come up as decimals, but I feel like I wouldn't be able to memorise each value of squar root 3/2 etc. Is there another way I can try get my calculator to give me values?
