I had a debate with a math teacher, and i really think i stumped her here. All teachers say that everything you learn in school is always applied somehow. I really cannot come up with anything that you can possible use this for. Neither could she, but she said she will be looking online, and will have an answer. I have looked for a while, and i would like to know if any of this stuff is useable to any of you, in any way, shape, or form.
logarithms y = log(x)
natural logarithms : y = ln(x)
exponential : y = ae^x
trigometry : sin(x), tan(x), cos(x)
