7 Famous Transcendental equations

Equations where the variable to be solved for appears only once, as an argument to the transcendental function, are easily solvable with inverse functions; Here we apply the method Lagrange.待求解变量仅以超越函数（transcendental function）的自变量形式出现一次的方程，可通过反函数（inverse functions）轻松求解；本文采用拉格朗日方法。
