1, r=a( 1-sinθ). It is said that this is the content of Descartes' last love letter, which contains an unforgettable secret. Polar coordinate images represent heart-shaped lines, which first appeared in a love letter written by Descartes to his favorite person! Of course, if you want the other person to understand, you need the other person to have a certain understanding of mathematics!

(x2+y2)- 16*abs(x)*y=225. My whole life is waiting for someone who can draw this function for me.

3, X2+(y+3√X2)2= 1. Draw a function image, which is a heart.

4. Y= 1/X, X2+Y2=9, Y=│-2X│, X=-3│SinY│ draw function images and display them in real time.

5、 128√e986。 Wipe off about half. If you don't, I love you.

6.r=a( 1-cosθ) or r = a (1+cos θ) (a > 0) Horizontal direction. Heart line.

7. x2+(y-3√x2)2= 1. A love line is formed on the axis, which is the exclusive "love curve" of the Department of Mathematics.

8. I am singing and you are singing. I don't want the sum of squares, just Tan.

9 、[-5e '(2i *π)+ 1 * 3]/2 = 1 * 4 .

5, 2, I, 1, 3, 1, 4 can be understood as "I love you all my life".

10, any real number, add 52.8, the result is multiplied by 5, then subtracted by 3.4343, the result is multiplied by 2, and finally subtracted by 10 multiplied by this number.
