Homework Statement
I'm currently new to Matlab and have just started trying to solve a few problems with it. So I have to make a program that will display the results of height and velocity of a falling object, as well as plotting the overall function.
My main concern is I am using an...

Hi I'm doing a question were I have 3 points and its asking me to find the normal to that plane, then it further asks to see if another point lies on that plane.
So due to reading the question I feel that it is suggesting that if I found the normal and then doted it with...

Hi I just have a problem in regards to setting up your partial fractions when doing nonhomogeneous differential equations using Laplace transforms.
I’m at the stage of getting the inverse Laplace of: (1-625S^4)/(S^3 (25S^2+1) )

Homework Statement
Ok so before I begin I've done my share of research and have had no luck as people seem to be moving to calculators for answers these days. I know my rectangular and polar conversions in AC but I haven’t done too much work with complex numbers.
I basically have two...
Ok I've cleared most of it up now but I have to ask one thing, how does - arcsin(x)*(1-x^2) - x^2*arcsin(x) = -arcsinx? I just don't understand the process of what's happening there.
Homework Statement
I'm trying to solve the derivative of this equation: 1-(x*arcsin(x))/√(1-x^2 )
I've straight away disregarded the 1 as it will be 0 so I'm left with -(x*arcsin(x))/√(1-x^2 ).
The Attempt at a Solution
I've applied the quotient rule and labelled U= -x*arcsin(x) and...
I see so your chose 2xy to cancel everything, so when it comes to this situation you are allowed to choose any term that will simplify the equation? Of course as long as your multiply top and bottom.
I'm still stuck now I'm up to dy/dx = [(2y-2xyln(y)]/(2x^2+2xy√y) its so close to the answer...
Homework Statement
I'm try to implicitly differentiate the function: xlny+√y=lnx
The Attempt at a Solution
And I got to the stage where I have: dy/dx = (1/x-lny)/(x/y+1/(2*√y)) which is where I have no idea on how to clean this up. Could someone please explain to me how to simplify a...
Hi I’m doing a project where we have to design a truss. I’ve made a design and I’ve figured out the reaction forces. There is a support in the middle and one on the left side, both of them are only vertical reactions and finally there is a load of 250N on the right being applied.
I don’t...
