Webhave seen that coshx gets close to e−x/2 as x gets large and negative. Therefore, sinhx and −coshx must get close together as x gets large and negative. So sinhx ≈ −coshx for large negative x. We can see this by sketching the graphs of sinhx and coshx on the same axes. y x sinh x cosh x Key Point WebDec 20, 2024 · Definition 4.11.1: Hyperbolic Cosines and Sines. The hyperbolic cosine is the function. coshx = ex + e − x 2, and the hyperbolic sine is the function. sinhx = ex − e − x 2. Notice that cosh is even (that is, cosh( − x) = cosh(x)) while sinh is odd ( sinh( − x) = − sinh(x) ), and coshx + sinhx = ex. Also, for all x, coshx > 0, while ...
