The production of some oil wells is better represented by a different exponential decline function known as hyperbolic decline, given by the following formula. y = y0 (1 + −1/ where y0 is the initial value, d is the exponential decline rate, and b is a hyperbolic factor (comonly called the "b-factor"). a. write a function that calculates the values of the above expression and writes t and y to a file named "oil. csv", similar to homework 5. the math library function pow(x, n) will return x . there is no ecl calculation for this assignment. below is a suggested format for a parameter structure and function. struct _oilparams { double y0; double d; double b; }; typedef struct _oilparams oilparams; void hyperbolicoil(double tmax, double interval, oilparams p) { } b. run your function from main() with the following parameters: tmax = 120 interval (step size) = 1 y0 = 50,000 d = 0.7 b = 0.5
