2,250 x 2+38-17.8686 = 520.1314-I love you all my life.

3. [(n+52.8) × 5–3.9343] ÷ 0.5-/kloc-0 × n = 520.1314 (n = any number)-I love you all my life.

4.r=a( 1-sinθ), r=a( 1-cosθ) or r = a (1+cos θ) (a >: 0) in the horizontal direction. Heart line.

5、r=a( 1-sinθ)

It is said that this is the content of Descartes' last love letter, which contains an unforgettable secret.

6 、( x2+y2)- 16*abs(x)*y=225

My whole life is waiting for someone who can hand-draw this function for me. For aesthetic needs, our heart-shaped graphics are often like this.

7、X2+(y+3√X2)2= 1

Draw a function image, which is a heart.

8、Y= 1/X、X2+Y2=9、Y=│-2X│、X=-3│Sin Y│

Also draw a function diagram, that is, ILVE.

9、 128√e986

Wipe off about half. If you don't, I love you.

The mathematical formula of I love you comes from a MV by Korean singer K.will, named "I Need You".
