I am trying to write a code that following this procedure: Guess theta = 0 Find Cl from L = W*cos(theta) so L = W Find Cd (where Cd is dependent on Cl) Find D from Cd Find theta as theta = asin(T-D/W) Use this new guess for theta and interate from step 2 until convergence of theta. T (thrust) ias found by calling a function, W = 35000. How would I write a code to find theta to plug it back in for Cl?

Using convergence for a fixed root iteration

I am trying to write a code that following this procedure:

Guess theta = 0
Find Cl from L = W*cos(theta) so L = W
Find Cd (where Cd is dependent on Cl)
Find D from Cd
Find theta as theta = asin(T-D/W)
Use this new guess for theta and interate from step 2 until convergence of theta.

T (thrust) ias found by calling a function, W = 35000.

How would I write a code to find theta to plug it back in for Cl?
