Question

For all questions, write commands in Matlab (or Octave) that you would use to solve the exercises, not the result.

For all exercises, you must write the commands that you would use to solve them, not the result 1. Compute sin(/5), e2v17 +4.(-33) 2. Write an anonymous function with the formula f) sin 2 3. 3. Write the function above so that it can be applied to vectors of arguments 4. Graph the function from-5 to 5 How would you find its zero around the point ro 3

Answer 1

1 clc 2 3 %%Part 1 4 yl sin(pi/5); 5 disp(y1): 6y2 -exp(2*sqrt(17)) + 4 * (-33); 7 disp(y2); 9 %%Part 2 10 fl 0(x) x"3 + sin(x) -2*x + 3; 12 %%Part 3 13 f2-(x) x.3 + sin(x) - 2.*x + 3; 14 15 %%Part 4 16 interval -5:0.1:5 17 plot(interval, f2(interval)); 18 19 %%Part 5 20 xfzero(f2, 3); 21 disp(x);

Output:
