Hi,

I am trying to solve two equations with two unkonwn variables. These equations are equal to zero so my way was first picking one of the variable to one side of the equations and equalize them and find the other unknown parameter. After that, by using the known parameter, I can calculate the other one. Here is the codes from mathematica :

In here, sf and [Beta]ex are unknowns. I decide to solve the equations for sf and then equalize them to find [Beta]ex. After getting [Beta]ex I could calculate sf.Code (Text):Ts[1,2] is :0.333184+sf (0.0559331+0.998885 Tan[\[Beta]ex])

Solution for sf with Ts[1,2]=0 = {{sf->-(0.333184/(0.0559331+0.998885 Tan[\[Beta]ex]))}}

Ts[3,4] is :13.0898+sf (1.00075-39.2433 Tan[\[Beta]ex-0.024 (1+Sin[\[Beta]ex]^2)])

Solution for sf with Ts[3,4]=0 = {{sf->-(13.0898/(1.00075-39.2433 Tan[\[Beta]ex-0.024 (1.+Sin[\[Beta]ex]^2)]))}}

However, I could not handle with that one. Please show me a way.

Thanks.
