how do I store a function into a variable and solve it?
显示 更早的评论
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
solv= solve(eqn,t)

There are likely an infinity of solutions —
syms t
y = 4*sin(2*pi*t) + exp(-t)./t;
figure
fplot(y, [0 10])
grid
.
The range for the question was -3<t<10
so I did this:
but it still says Unable to solve symbolically, returing to numeric solution using vpasolve
in sym/solve line 304
In (line 7)
syms t
y = 4*sin(2*pi*t) + exp(-t)./t
eqn = y -- 0
figure
fplot(y,[-3 10])
grid
solv =solve(eqn,t)

There remain an infinity of solutions!
