I've already taken physics courses and like them. But that just tells me that I like physics. It doesn't tell me anything about engineering as far as I can tell. I assume that's in Israel. It's too bad the US doesn't have engineering courses that early. Well maybe some schools do but it has...

Uhh.. thanks for your opinion I guess... Of course one could make more money being an investment banker or lawyer if you only care about money. I am hoping that some people on physics forums have a non-monetary interest in physics and engineering. And obviously I'm not asking whether...

I find it odd that most people commit to engineering before they've even tried taking an engineering course. People who go straight to four year colleges generally get admitted to an engineering major in high school. Likewise transfers frequently haven't had a chance to take any engineering...

Thanks for the suggestion and you were correct about which type of algebra I'm talking about.

I've been doing the intermediate math classes like calculus and differential equations. I'm doing okay, but not great. What holds me back getting a 100% in these classes is almost always the algebra. I make stupid algebra mistakes and honestly am not completely comfortable with some concepts...

I think you had a typo in your previous post which is what was confusing me. (2pi instead of pi/2) Thanks for the help.

Thanks hunt and ray, I forgot about about the basic definition of the laplace transform. With that said, I don't remember doing any examples using heaviside functions with the basic definition. Is there a generalized form of hunt's second equation?

I thought I already attempted to write it as a heviside function in my attempt...

Does RHS mean right hand side?

I corrected the typo. Thanks.

Aside from chemical engineering or biophysics, to what extent do physics and engineering masters programs require you to have had a second semester in inorganic chemistry? Thanks.

Thanks. I guess my question should have been, "why doesn't water have the shape of a wave when it freezes?"
