I hate laplace transforms. I failed my test on solving IVPs with them . Just had to vent. Oh well, lowest test grade is replaced by final if final is higher. Anyone got any tips for learning laplace transforms? I semi need them. I have to retake the class anyways next semester, but it would be good to get an A this semester so i know im ready for the course again. Also, to any mechanical and/or biomedical engineers. How often do you really use differential equations? Im guessing quite often, but am just curious.

 

No real tips other than do a bunch of them and become familiar which the different forms so you recognize with transform to use. I learned this in EE, controls theory and diffy-Qs. The long algebra and substituting back and forth is what I found complicated; the individual steps aren

 

im studying that right now for signal processing for my computer engineering degree. it was last weeks topic, i still have to go over, it didnt seem very difficult.

 

I was an EE and Computer E double major.

I think the single most important part of being able so solve laplace transforms well (and quickly) is to be able to recognize the form such that you can factor them quickly.

A good tip for that is to buy a Schaum's Outline on Calc I. Sold at any B&N store. Repitition is the key to being proficient here. Unfortunately that can be boring and take a lot of time.

Good Luck!

I didn't have too much trouble with Laplace Transforms, basically because our prof handed out a small booklet with about 50 common "forms" that you would use - it gave solutions for each type. Fairly simple.

To do it straight off the top of my head, though, would be a royal pain. I doubt I can do it now - I don't use it enough.

What it might be used for, though, is simulation of systems. If you're into thermodynamic systems, especially, they may come in handy. That said, if you're into thermo, you're probably using something else that's either more complicated or else a little more friendly to changes.

 

I'm sorry. Does this have something to do with gender bending?

 

Thinking back to Differential Equations, the only way to become proficient at solving LaPlace transforms it by doing A LOT of them. . . Beyond that, good luck!!!!
