I am trying to calculate this function: 𝑓(𝑡) = 4(sin(2𝜋𝑡)) + exp(−𝑡)/𝑡

but it keeps on telling me 'Error using sym/assume Too many output arguments.'

syms t

y = 4*sin(2*pi*t) + exp(-t)./t;

eqn = y == 0

eqn =

solv= solve(eqn,t)

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

solv =

98.5

There remain an infinity of solutions!

Hi thank you for your help, I used pasolve to gives such one value out of an infinite number of possible solutions
