Suppose I write a function f(a,b,c,d).
I want to solve it using solve as
solve(b=1/f(a,b,c,d))
but whenever i used the above it gives error, showing use symb variable.

You defined a,b,c and d as symbolic ? You want to solve b=1/f(a,b,c,d) for b ?
Then
bsol = solve(b*f(a,b,c,d)==1,b)
should work.

Hi,
You can use "syms" to create symbolic function with four arguments:
syms f(a,b,c,d)
here, f is abstract symbolic function. It does not have symbolic expressions assigned to it.
Then, specify the following formula for f.
% formula for f
After that, you can use "solve" function:
solve(b==1/f(a,b,c,d))
