What is the heart-shaped function expression?
The expression of the heart-shaped function is r=a( 1-sinθ). R=a( 1-sinθ). This function has two variables, which can be assigned to a and then solved. The function image is a heart-shaped line. This equation is also called Cartesian love coordinate formula.

I love you, that is, the mathematical equation r=a( 1-sinθ). Both mathematics and literature originate from the way of nature. Numbers, geometric figures and various meaningful laws are all part of nature, and mathematicians hope to express the essence of these natural phenomena with concise mathematical language.

The definition of the function gives a set of numbers A, and the corresponding rule F is applied to A, marked as f(A), and another set of numbers B is obtained, that is, B=f(A). Then this relationship is called functional relationship, or function for short. The concept of function includes three elements: definition field A, value field C and corresponding rule F, among which the core is corresponding rule F, which is the essential feature of function relationship.
