    How Do You Calculate Max Relative Error in Projectile Motion?

    ds/s = 2dv/v + 2(cos2t/sin2t)dt If you consider here sin2t=x,then (cos2t dt/sin2t)=dx/x Hence ds/s=2dv/v+2dx/x substituting dv/v=10 and dx/x=10 ds/s=40%. Hence relative error of s is 40%

    Robot Location Triangulation Using IR Beacons: Improving LED Sensitivity

    I think you might be knowing the wavelength of current leds.Just search for other type.I think we can find because the basic difference between two types is that surface emitting led emits in a circular fashion and edge one in elliptical pattern.I din't understand what is meant by odd manner.

    Graduate How can I graph this equation (Rayleigh Plesset for sonoluminescence)?

    Dude what is this P(t)? Is it any other equation or we have to make it as a subject like P(t)= something and plot it?

    Robot Location Triangulation Using IR Beacons: Improving LED Sensitivity

    My dear friend,there are 2 types of leds.Edge emitting and surface emitting.Of them edge emitting leds are better.Just check the properties of it.

    Undergrad Need Help with Solving an ODE in Calculus 1?

    dx/dt = 2000-500x/100 =>dx/dt=20-5x =>dx/20-5x=dt=>(dx/4-x)=5dt Integrating it,-ln(4-x)=5t+k(integrating constant) =>x=4-a*exp(-5t) (ln(x) is one of the basic functions in maths)

    Graduate Solving a Recursive Multivariable Equation

    I tried it and I found that there should be another condition w.r.t. to k too.

    Undergrad Finding general formulas for a series of numbers.

    We can't say like that because some follow a series and some follow logic.I'll give examples of both.Series'll follow a specified formula. Eg. of logic series:1,2,2,4,3,8,4,16,5,6etc. In this odd positioned nos are 1,2,3etc and even positioned nos are 2,4,8,16 etc.

    Graduate A Cubic Function and a Straight Line with One-variable Calculus

    FOR PART 4: You just expand RHS of give eq. in and equate coefficients of x^2 on both sides and you'll get it.

    Undergrad Convergence/Divergence of an Integral

    My method is that I draw a rough sketch of function.If f(t)→ 0 while t→∞,then we can say that integral is convergent as integral is area under the curve.

    Graduate Can someone explain this to me please?

    The condition y(1)=0 is given in order to find constant.THE PURPOSE OF GIVING BOUNDARY CONDITIONS IS TO OBTAIN CONSTANTS AFTER INTEGRATION.

    Confusion regarding negative resistance circuits

    Negative resistance is just a property shown by some elements like UJT(in normal ac circuits),GUNN DIODE(in microwave circuits) etc.All of them exhibit that property in a range of ac voltage.Hence as far as I know,there is no such dc circuit.

    Understanding Nyquist criterion and plot

    Sorry for late reply.I understood that you are confused because you are thinking that we Plot magnitude Vs frequency.It's not the case.We are plotting Re(G(jw)H(jw)) on X axis and Im(G(jw)H(jw)) on Y axis as Frequency increases(we are not showing frequency).We are interested in stability etc. of...

    Can This Circuit be Used for Charge Recycling?

    I think definitely we can do it because the capacitors are at output section and definitely it will get some output either voltage or current.Isn't it?

    Can This Circuit be Used for Charge Recycling?

    As far as I know a capacitor needs a resistor to discharge.So I think in above circuit considering ideal situation,they can't discharge.If I m wrong please tell me.
