AI Drawing Prompt Reference

Draw a normal distribution curve and its geometric analysis. Start with two curves: one standard normal curve and one transformed curve. Shade the area under the curve from zero to one and label the integral value. From the origin, draw three vectors along the x-axis, y-axis, and diagonal. Select several key points on the curves, connect them to form a polygon, and add arcs, segments, and angle marks. Include multiple auxiliary points, measure and display distances between points, and show the area between the curve and axes. The overall figure illustrates the geometric properties and transformations of the probability density function.
