Hi 

how can i solve this integral in term of x

int(d*e^(-b*x)/(((a*e^(-2*b*x)+c*e^(-4*x)))))

Hi

how can i find the answer if this integral analytically

int(exp(-b*x)/(exp(-2*b*x)*a+exp(-4*x)),x);

Hi

how can i solve this

dx+4*x*dy/y = dy*a*y^(-6*b-1)

to find x in terms of y

Hi

how can i find x in terms of y(x)

 

y(x)=integral exp(-x)/(sqrt(exp(-2 x) + a) - sqrt(a)) dx = e^x (sqrt(a + e^(-2 x)) + sqrt(a)) - log(sqrt(a + e^(-2 x)) + e^(-x)) + constant
(assuming a complex-valued logarithm)

Hello everybody

can anybody help me solve this differential equation please?

 

d^2y(t)/dt^2-dy(t)/dt*1/y(t)=a*y(t)^2
