I have an equation
a_eq*sqrt(P1/B) = ellipticK(k1^2) - ellipticF(m1,k1^2)
B = 1.3761E-4,
P1 = 0.4905,
a_eq = 9.5E-3,
k1 = sin{(theta +alpha +pi)/2} a
m1 = arcsin[ sin{(alpha + pi )/2}/k1].
Here, I want to solve for theta and for that I have to solve for k1.
How to solve for k1 in this equation?

 Accepted Answer

a_eq*sqrt(P1/B) = ellipticK(k1^2) - ellipticF(arcsin[ sin{(alpha + pi )/2}/k1],k1^2)
for k1.
Once you have k1, you can solve for theta.
