How to plot a formula?

Question

C++ / C#

Hello, you need to build on the form "Traktrisa" according to the formulas.
x=A(cos(t)+ln(tg(t/2))
y=Asin(t), 0<= t <=2π
I have absolutely no idea how to do this, thanks in advance for any answer.

Answer 1

There is a Chart control. Its use is very similar to using the object of the same name in Excel.
Determine the range of t values, calculate x and y. You write the received data to an array, feed the array to Chart. Everything, the schedule is built

Answer 2

The form has graphics that can draw points, lines, and more. Here's a chart for them and draw.
