Hyperbolic Functions - Math is Fun
WebGraphs of the hyperbolic functions. It is easy to develop differentiation formulas for the hyperbolic functions. For example, looking at sinhx sinh x we have d dx(sinhx) = d dx( ex−e−x 2) = 1 2[ d dx(ex)− d dx(e−x)] = 1 2[ex +e−x] =coshx. d d x ( sinh x) = d d x ( e x − e − x 2) = 1 2 [ d d x ( e x) − d d x ( e − x)] = 1 2 [ e x + e − x] = cosh x. WebApr 5, 2024 · (a) Find the McLaurin series of f (x) = cosh (x). (b) Use the above result to show that cosh x > 1 + 2 1 x 2 for all x . (c) Graph cos x and 1 + x 2 /2 to illustrate the … WebJun 30, 2024 · We give a precise definition of tangent line in the next chapter; but, informally, we say a tangent line to a graph of f at x=a is a line that passes through the point (a,f (a)) and has the same “slope” as f at that point . The function f (x)=e^x is the only exponential function b^x with tangent line at x=0 that has a slope of 1. flower delivery harrison ohio
