I am a new user of Mathematica. I want to solve the following equation
a*Tan[a] = Sqrt[(52.7531 - a^2)]
a is a real value. I used the
Solve function, but I am not getting the right answer.
Solve[a*Tan[a] == Sqrt[(52.7531 - a^2)], a, Reals]
I am doing something wrong. Could anyone tell me what it is? Thanks in advance.
