How can I solve it ?? Help please

How can I solve this Equation Sin(2t)-3t=3t-cos(t) without using ((solve)) Thank you

Answer 1

[KSSV]

syms t 
eqn = sin(2*t)-6*t+cos(t)==0 ;
s = solve(eqn,t)

Warning: Unable to solve symbolically. Returning a numeric solution using vpasolve.

s = 

0.23845729337266814001123439439291

Answer 2

You said without using ((solve)). Try fzero()

f = @(t) sin(2*t)-3*t-3*t+cos(t)
t_sol = fzero(f, 0)

Result

>> t_sol
t_sol =
    0.2385

This solution does not require any additional toolbox.

Answer 3

[KSSV]

f = @(t) sin(2*t)-6*t+cos(t) ;

t = linspace(0,1,10^6) ;
y = f(t) ; 
t0 = t(abs(y)<=10^-6)

t0 = 0.2385
