Question: Consider the expression where . The series approximates the sine function , i . e . , . . We can compute the sum using
Consider the expression
where
The series approximates thesinefunction ie
We can compute the sum using the recurrence relations and with initial values and
Write a function named computesinesumerrthat accepts two input variables, a real value xused in the sum, and the positive real value errorTol.
Add commands to the function that compute the expression until it converges to within errorTol. Specifically, convergence occurs when the relative absolute error is less then errorTol. Do not use the factorialfunction
Assign the value of the sum to the output variable S
Assign the number of terms in the sum to the output variable noTerms. Notice that noTermswill be equal to because the sum starts indexing at
If errorTolis negative, then assign the empty vector value to S and assign to noTerms.
Note the value of the variables xand errorTolare defined as inputs to the function. Do not overwrite these values in your code. Be sure to assign values to the output variables S and noTerms.
