Hi matlab experts, I am trying to solve the equation below where T is the time. The solution was just one negative number which should have different values because of the sin and cos functions. I tried this in TI-89 calculator and it gave me different values in predefined period. My question is, can the period of time through which the solution occurs be defined in matlab, (eg, 0<T<2). so the solution will be within this range.

The code >> syms T >> TT=(2*pi*1.225*((1.5)^2)*exp(-0.1)*(cos(2*pi*T-0.1)+sin(2*pi*T-0.1))); >> vpa(solve(TT,T))

Thank you, Aziz
