It is an odd function defined by the reciprocal identity cot (x) = 1 / tan (x). The secant function is the reciprocal of the Cosine function. Its vertical asymptotes will occur whenever the cosine is 0. at +- (2n+1)pi/2. In other resources, it is easy to identify the vertical asymptotes for the secant graph by solving the inequality -π/2 < βx + c < π/2. Divide each term by 2 2 and simplify. Given a rational function, we can identify the vertical asymptotes by following these steps: Step 1: Factor the numerator and denominator. 4. The value of sec (θ ) when cos (θ ) equals zero is thus said to be undefined. Start by drawing three consecutive asymptotes. Secant is 1/cos x….when x approaches pi/2 or 3pi/2, cos x approaches 0 which will be the asymptotes Draw the vertical asymptotes through the x -intercepts (where the curve crosses the x -axis), as the next figure shows. To find the vertical asymptotes dete You can graph a secant function f ( x) = sec x by using steps similar to those for tangent and cotangent. As the value of cos (θ ) approaches zero, however, the value of sec (θ ) tends to infinity. There are vertical asymptotes at each end of the cycle. x = − π 2 x = - π 2.
