Thanks for the response Redbelly98. I got it from an exam question. The question said the same force is used to push into & pull out the bar magnet. From that statement I assume the speed of the bar magnet is the same in both situation. The problem is the marking scheme for that question said...

A simple experiment of pushing magnet bar into solenoid & pulling it out from solenoid. If galvanometer is used to measure magnitude of induced current, galvanometer will show greater deflection when the bar magnet is pushed into the solenoid but the deflection will be less when the magnet is...

n and T are integers and always positive.

What do you mean with sign of n and T ?

∂ω2 = (1-cos2(Δt)e-2γ(t))/(nTtsin2(Δt)e-2γ(t)) n,T are assumed as constants. How can I use Mathematica to find the values of Δ and t that will give the minimum values for ∂ω2 ?

I have a gamma function in the form of Gamma(s-1) where s can take only positive values. How can I plot this function for different value of s using Mathematica ?

how should I define my function ? I keep getting 'm power error'

still not clear..

My function is; y(x,s)= 1-(cos[(s-1)arctan(x)]*gamma(s-1))/(1+x^2)^(s-1)/2 varible x will have range from 0 to 10. At one time the s value will be constant e.g. s = 3 but I want to change s for different values( is there any commands in MATLAB that will allow me to do this ?). I tried many...
