Now, before you start rolling your eyes and muttering “math is boring,” let me tell ya, these babies are anything but dull. They’re like the wild child of trigonometry, with a little bit of craziness thrown in for good measure.
So what exactly are hyperbolic functions? Well, they’re basically just extensions of the regular old sinusoidal functions we all know and love (or hate). But instead of dealing with circles and radians, these bad boys use hyperbolas which is where the “hyper” part comes in.
Now, if you’ve ever seen a hyperbola before, you might be wondering why anyone would want to deal with it. Well, for starters, they have some pretty cool properties that make them useful in all sorts of applications (like physics and engineering). And secondly, they just look really freakin’ awesome!
So Let’s get right into it with the world of hyperbolic functions and see what makes ’em so special. First up is sinh which stands for “hyperbolic sine.” This function takes an input x (which can be any real number) and returns a value that represents how far along the curve of a certain hyperbola you would have to go in order to reach a point with coordinates (x, sinh(x)).
Now, if you’re thinking “wait, what? That doesn’t make sense,” don’t worry it might take some getting used to. But trust me, once you start playing around with these functions and seeing how they work in practice, everything will become crystal clear (or at least a little less blurry).
Next up is cosh which stands for “hyperbolic cosine.” This function takes an input x and returns a value that represents the distance between the origin and a point on another hyperbola with coordinates (x, cosh(x)). And just like sinh, it can be used to solve all sorts of problems in physics and engineering.
But wait there’s more! We also have tanh which stands for “hyperbolic tangent.” This function takes an input x and returns a value that represents the ratio between the height (or y-coordinate) of a point on one hyperbola to the height of another point with coordinates (-x, cosh(x)). And if you’re wondering why we need all these different functions when we could just use regular old trigonometry instead… well, that’s where things get really interesting.
You see, while sinh and cosh might seem like strange bedfellows at first glance (especially since they involve hyperbolas rather than circles), they actually have some pretty cool properties when you start playing around with them. For example:
– They are both even functions, which means that if you flip the input x over to -x, the output will be the same as before. This can come in handy for all sorts of calculations (like finding the area under a curve or integrating a function).
– They have some pretty interesting limits when x approaches infinity or zero. For example:
sinh(0) = 0
cosh(0) = 1
tanh(x) approaches either +1 or -1 depending on whether x is positive or negative (respectively).
– They can be used to solve all sorts of problems in physics and engineering, from calculating the trajectory of a projectile to designing circuits for electronic devices. And if you’re wondering how they compare to regular old trigonometry… well, let me just say that there are some pretty big differences (especially when it comes to dealing with hyperbolas instead of circles).
Whether you’re a math whiz or just someone who likes to dabble in science and engineering, these babies are definitely worth checking out. And if you ever find yourself struggling with any of them (or just want to learn more), don’t hesitate to reach out for help we’ve got your back!
