hw2.5 The Taylor series for the sine function is (25 Points) (hw2.5.1) 3! 5! Write a MATLAB function called my-sine that uses the Taylor series expansion to evaluate sin(x) at a use印rovided z-value, to a user-defined accuracy tol, which specifies the maximum relative true error(ie., the relative error compared against the built-in function sin(x)). Inputs: x The r-value to evaluate. tol The tolerance to which the sin(z) function should be evaluated. Outputs: f The estimate of sin(x) n The number of terms in the series required to achieve the desired accuracy. Driver: hu2 5.m Prepare a figure that plots the number of terms required vs. logiotol for1, 5,10, and エ= 20. Use a logspace-generated list of tolerances ranging from tol-1 (100% error) to tolle 9 Your plot should include proper labels, a title, and a legend.

Expert Answer

 

This is the sin function.

function [y n] = sine(x, tol)
i = 1;
sign = 1;
y = x;

while abs(y – sin(x)) > tol
i += 2;
sign *= -1;
y = y + sign*(x^i)/factorial(i);
end

n = (i + 1)/ 2;
end

Driver

figure();
for x = [1 5 10 20]
count = [];
tols = logspace(0,-9);
for tol = tols
[y, n] = sine(x, tol);
count = [count n];
end
plot(tols, count);
hold
end
xlabel(‘0 < tolerance < 1’) % x-axis label
ylabel(‘iterations’) % y-axis label
