---- 2/3sin-1x
Depends. Slope of tangent = instantaneous rate of change. Slope of secant = average rate of change.
All of them...?
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.
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
yes
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.
Secant is a trignometric function. In a right triangle, the secant of an angle is the hypotenuse over the adjacent side. It is also the inverse of cosine. For example secant(x) = 1/cos(x)
A secant line is a line that cuts a circle in two places.
