Solving for beta using symbolic math in MATLAB with constraints

[tigertan]

Homework Statement

hey there,
i'm trying to solve for beta which I tought i'd easily be able to figure out using MATLAB (i'm not the most proficient MATLAB user) but i can't get it to work..

Homework Equations

The Attempt at a Solution

My code is as follows:

clear all;
close all;
clc;

m = 8;
a = 0.3;
l = 0.5;
g = 9.81;
I2y = 2;
I2z = 0.2;
omega = 7;

syms b

omega^2=(m*g*l*tan(b))/((sin(b)*(m*l^2+I2y-I2z)+m*a*l)

I would like to solve for beta within the range of -pi to pi

You are going to have to be a little more specific for us slow folks.

What is beta? How does the code snippet you provided figure in the solution of beta?

Please follow the Homework template so we don't have to play these guessing games.

sorry, beta is b
i would like to solve the last equation. I would like to solve for 'b'. It is the only symbolic as the constants for the other letters are defined above

I'm not a Matlab expert, but I don't think it's used as a computer algebra system, which is what you require to isolate beta. Now, if you just want to calculate a value of beta which satisfies the equation you have, knwing the values of the other variables, you can use Matlab to do this, but it requires extra programming. You can't just toss an arbitrary expression at Matlab and have it provide a solution.
