What function is the love formula?
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".

Characteristics of functions

limitations

Let the function f(x) be defined on the interval x, if there is m >;; 0, for all X belonging to the interval X, there is always | f(x) |≤ m, then f(x) is bounded on the interval X, otherwise F (x) is unbounded on the interval.

monotonicity

Let the domain of the function f(x) be D, and the interval I is contained in D. If for any two points x 1 and x2 on the interval, when X 1
