Since I would consider this a typical proportional problem, I wonder that too?The problem is attached. It is triangle and its peak is having value 1
the sides are at a and -a. The new point is on a/4. from which i have drawn perpendicular line
i want to know what is the value of that point on y-axis scale.
book says it is 0.733
Are you sure you don't have any more information on a?
If a can be any number, triangle height y can be 0<y<1 ?
