11. The dots on the secant line " AE " are equally spaced. 12. For integrating powers of secant , try rewriting the integral in two different forms. 13. Why did he never mention the secant , with which he in fact operated? 14. This slope is determined by considering the limiting value of the slopes of secant lines. 15. Tangent and secant lines ( " standard lines " ) are represented undistorted. 16. The article Derivative of Secant Function does not seem to add any value to Wikipedia. 17. :A secant joins two points on a curve, a tangent touches just one. 18. If is the point of intersection of two tangents, no secant can pass through. 19. The Euler numbers appear in the Taylor series expansions of the secant and hyperbolic secant functions. 20. The Euler numbers appear in the Taylor series expansions of the secant and hyperbolic secant functions.
