Scott Fitzgerald 10 years ago I'm having difficulty understanding the concept of a secant line as it pertains to a sine graph.

WebTangent Lines and Secant Lines (This is about lines, you might want the tangent and secant functions). A tangent line just touches a curve at a point, matching the curve's slope there. (From the Latin tangens "touching", like in the word "tangible".) A secant line intersects two or more points on a curve. (From the Latin secare "cut or sever") They are … WebFor secant functions, say y = sec (x), the values for which the function is not defined are x = ± [ (2n +1)π] / 2 and the asymptotes are at x = ± [ (2n +1)π] / 2. Near those values of x for which each function is insignificant, the values of the trigonometric functions are unbounded. Hence, the amplitude is insignificant for these functions.

Webcosecant, secant and tangent are the reciprocals of sine, cosine and tangent. sin-1, cos-1 & tan-1 are the inverse, NOT the reciprocal. That means sin-1 or inverse sine is the angle θ for which sinθ is a particular value. For example, sin30 = 1/2. sin-1 (1/2) = 30. For more explanation, check this out.
