The derivative of a function can be portrayed as d/dx(function)=(derivative of a function) and y'=(derivative of y). The more apostrophes you have in the derivative the better, so realistically you should have something that looks like y''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''=x^2 By taking the derivative of a value, you take the power (number in exponent) and multiply it by the coefficient (number infront, if there is none then its 1*power) then you replace the exponent with the previous exponent, minus one. you do nothing with the variable. example lets have some examples y=(@Duster 's fat head)^420 y'=420(@Duster 's fat head)^419 y''''''''''=fuck you y''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''=the mitochondria is the powerhouse of the cell congratulations you can now take calculus at an upper 4th year level
Dude pls. *Rolls eyes* Call me anything but don't call me useless. That triggers me big time, I am anything but useless! -_-
B-b-but... what if you want to solve a second order differential equation modelling the motion of a particle undergoing damped oscillation?
Not everyone's a fucking physicist! That said, regretting taking physics just cuz of calc. ;_; Seriously tho, I think statistics / probablity, basic algebra, basic geometry and arithmetic is enough for most real world situations.
With regards to mathematics, for most real world situations you just need to know addition, multiplication, subtraction, division, percentages and angles.
Complex analysis isn't always required. Trial and error exists for a very good reason. Now with that being said, think of how many explosions happened with trial and error in terms of making the H bomb the first time :D
i was assuming we were taking "real world situations" as "shit people do every day" naturally as you specialise in something, you'll need something more, but I'm pretty sure a retail grunt doesn't need more than what I stated
