So, let us see the way to draw graphs of an equation in Windows 10. To do this, begin by writing your equation. For example: y=x+3 or y=sin(x)+cos(2x). Next, use Lasso tool to select the equation ...

cos(θ) is the x-coordinate of the point P and, sin(θ) is the y-coordinate of the point P. This applet shows how the graphs of sin(θ) and cos(θ) follow directly from the definition of these functions.
