Question 1002878
the length of a heavy cable hanging under gravity is given by
l=2csinh(L/2c)
find the value of(l) when c=40 and L=30 using the exponential form and check your result using the hyperbolic function on your calculator
------------
l = 2c*sinh(L/2c)
l = 2*40*sinh(30/80)
l = 80*sinh(0.375)
l =~ 30.708
