Question

I tried to run the code but am receiving an error of " no matching function call"im not sure why this is the case. The problem should be in the main . However, I think u have used correct procedure for calling function

Answer 1

Now I understand you want to return the sine and cosine through the function arguments. It explains why you had void set as function return type.

The problem is:
1. You should've passed <x> and <n> by value because they are not changed in the `calculate_trig_from_series` function. You need to pass <sin_val> and <cos_val> by reference in order to have their updated value reflected in main function.

2. You shouldn't chain the call to `calculate_trig_from_series` function with the data to be inserted into output stream. The function doesn't return anything so there is nothing to be inserted to the output stream. You call the `calculate_trig_from_series` function in a separate line.

Answer 2

void calculate_trig_from_series

This function doesn't return any valid data to be inserted into the output stream `cout`.

Super bro. Your help has been invaluable. I can see my mistakes now. And the program works like a charm. God Bless🙏🏾

Answer 4

I have changed the type to double but still some problem

Answer 5

What is it exactly are you trying to do?
Now the function name is gone, only the return type is left.
And you have 2 return statements at line 27.

Answer 6

I'm trying to calculate the sine and cosine value using the formulas in the function and be able to pass parameters in main
