Hi:

how i find the roots of the below equation?

eq := tan((1/2)*x)-tanh((1/2)*x) = 0

Hi:
i have two functions(f(x)&g(x)),i calculated values this functions with numerical method(dsolve,numeric),
now i will plot the f(x)-g(x) for 0<x<1,how do this work?

Hi:

i will seprate coefficients of a,a^2,a^3 and this coefficients equivalent zero(0) in EQ below,how can i do this?

EQ:= 3.522088319*10^(-10)*a^2*q21(T)+3.522088319*10^(-10)*a^3*q22(T)-6.094634327*10^(-16)*a*q41(T)-6.094634327*10^(-16)*a^2*q42(T)+6.094634327*10^(-16)*a*q51(T)+6.094634327*10^(-16)*a^2*q52(T)-1.106493792*10^(-9)*a*q11(T)-1.106493792*10^(-9)*a^2*q12(T)+2.429209785*10^(-24)*a^2*(diff(q21(T), T, T))+2.429209785*10^(-24)*a^3*(diff(q22(T), T, T)) = 0

Hi:

i follow the code newton raphson for solve system nonlinear ODE in maple,every body have code for it?

Hi:

i will calculation of value function in every step by 0.001(x=0,x=0.001,x=0.002,...x=10):

my function:

f(x)=x^3+2*x+1

my domain:

0<x<10
