cant do it. pls help. it's urgent

y - xtanθ = z/cosθ Find θ in terms of x,y,z equation seems so simple, but can't do it

may i know how do i use numerical method to solve this trigo+algebraic equation? i need to equate the equation θ in terms of b,c,m,z,p Using Newton Raphson? (i donno how to use software, only know how to use handwritten)

and also how if i want to use numerical method? how to use it ? Matlab?

b,c,m,z,p are the fixed constant, they will be known later. Somehow i can't get θ if i use HallsofIvy's approach because the existence of fourth, third, second, first degree of cos θ

Anyone here can lend a golden hand?

Thanks for ur precious reply! Somehow i still have to go through this question.. does it has any alternative method?

b2cos2θ+2cosθ(-mb+bc2-bz-bcsinθ)+2sinθ(cm-cz)-c2sin2θ=p How to get θ in terms of b,c,m,z,p The equation i formed to calculate the dynamic PLs, anyone can help to solve this, i would much appreciate! I am doing my FYP!

but i tried both methods, it just make the question more complicated than ever. I used to squaring up x and y, and add both together, I am sucessfully eliminate θ1, but others seems to have trouble.

Find θ1,θ2,θ3 in terms of x,y,z and p. Sorry for the inconvenience.
