Maple

I am trying  to solve a first order differential equation.  But the maple is not able to solve. Please help me in finding the solutions...

Exact solution is not necessary. Solution in the series expansion is also be very helpful.

Maple

Given a lagrangian  in general relativity , how can I calculate equation of motion using euler lagrangian equation in maple software ?

the lagrangian is

`L = 1/2 g[mu,nu] diff(x[~mu], lambda) diff(x[~nu],lambda)`

here lambda is the affine parameter.  and the metric is

metric coordinate = (t,u,x,y)

## HeunB function expansion...

Maple

I want to series expand the HeunB function. But I am facing some problems with this. please help. Here is the given HeunB function.

HB1 := HeunB(5/2, -5^(1/4)*(2*M - R)/sqrt((2*M - R)*(4*M - R)), (17*sqrt(5))/10, (3*5^(3/4)*(2*M - R))/(2*sqrt((2*M - R)*(4*M - R))), 5^(1/4)*sqrt((2*M - R)*(4*M - R))*r^2/(2*(2*M - R)*R^2))

Here M, R are arbitrary constants.
