draw a line vertical from where strain is equal to 2.5%.
where it hits your stress vs. strain curve, draw a line from there to the origin
the slope of that line is your Es or secant modulus

secx is the inverse of cosx. secx=1/cosx. A secant is also a line drawn through the graph that touches two points on a function.
Speed (in the radial direction) = slope of the graph.
Any graph where the independent variable (x-axis) ranges to + infinity or - infinity , or both.
It is like the sine graph except that, instead of going below the x-axis between π and 2π radians (180 and 360 degrees), it is reflected in the x-axis. An d so on: every time the sine graph would have gone below the x-axis, this one has the reflected shape above the axis.
