If you have a stress strain curve that is non-linear the secant modulus is the slope of a straight line connecting the zero strain point to the final strain point of interest
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
a secant is a line containing a chord. A secant is a line that intersects the circle twice(or passes through a circle)
Cosine.
Substitute secant(x)=1/cos(x) into your equation, and you should be able to solve from there.
I am almost positive that it isn't because a secant is an extended chord so it goes out of circle. So no it is not.
The secant modulus is the total stress or strain on an object as described by a stress-strain graph. The tangent modulus is the marginal strain.

This question probably is referring to a 2% secant modulus, which can be the tensile, flexural or compressive modulus (slope of a stress/strain curve) of a material that is determined from calculating the slope of a line drawn from the origin to 2% strain on a stress/Strain curve.
that depends; if you are worried about deflection under load the higher the better to reduce deflection; but if you are worried about stress under temperature or constant input deflection, the lower the better.
You can calculate the cosine and then its reciprocal.
Young Modulus is the slope of the stress-strain diagram in the linear elastic region. This is the most common use of modulus. As the material goes non-linear in the stress strain curve, thre slope will get increasingly lower. In this case one connects the end points of the stress strain diagram at the point of interest with a straight line. The slope of that straight line is the secant modulus.

That is the correct spelling of the geometric term "secant."
Sometimes
a secant is a line containing a chord. A secant is a line that intersects the circle twice(or passes through a circle)
The tangent secant angle is the angle between the tangent to a circle and the secant, when the latter is extended.
