Use the value of the given hyperbolic function to find the values of the other hyperbolic functions. sinh X = 6 cosh(x) tanh(x) : csch(x) = sech(x) coth(x) = Need Help? Read ItConsider the equation of the tractrix y = a sech (x/a) - Va2 - x2, a > 0. (a) Find dy/dx. dy dx (b) Let L be the tangent line to the tractrix at the point P. When L intersects the y-axis at the point Q, show that the distance between P and Q is a. First, find the equation of tangent line through P = (Xo, yo). y - a sech-1 40 + ( x - Xo) a XO When X = 0, y = So, Q is the point O Finally, using the Distance Formula from P to Q, we show that: d = V xo2 + = a
