Please answer it correctly thank you. Need the code for matlab

Consider the following parallel RLC circuit: The equation that identifies the response of a parallel circuit shown above is s = -1/2RC plusminus squareroot (1/2RC)^2 - 1/LC (a) Determine the values of s for a resistance of 200 ohm. (b) Create a vector of values of R between 50 to 900 ohm with a step size of 2. Evaluate s at all values of R. (c) Plot value of real and imaginary parts of s vs. R (d) What is the minimum value of R that yields pure real value of s. (e) The resonant frequency of a parallel RLC circuit is given by: f_r = 1/2 pi squareroot LC Compute the resonant frequency of the above circuit
