Question

please answer the question using matlab

Problem 3. Use the zooming technique to find solutions of the equation 8-3sin(x) (you need to include your mat Lab commands to receive any point, and be sure your answer is valid to at least two decimal places).

Answer 1

Zooming technique means looking at the points of intersection of the two graphs mentioned in the matlab code and approximate it visually.

x=-5:0.01:5;
y1=x.^2;
plot(x,y1)
hold on
y2=8-3*sin(x);
plot(x,y2)
legend('x^2','8-3sin(x)')
8-3sin(x) 6.5 6.4 6.3 6.2 6.1 5.9 5.8 5.7 2.35 2.4 2.5 2.8 2.45 2.55 2.6 2.65 2.7 2.75
it is around 2.475
