Question

I have some mathlab questions want to ask, how to save f(-.05) and f(1.1) that two product in one file?

a52x4 3x3 - 2x2 x f(x) (30x) 1-coS Calculate f(-0.5) and f(1.1) and save their product as A1.dat

Answer 1

Hey,

Below is the answer to your question

clc
clear all
close all
f=@(x) x^5-2*x^4+3*x^3-2*x^2+x-1-cos(30*x);
a=f(-0.5);
b=f(1.1);
a*b
file=fopen('A1.dat','w');
fprintf(file,'f(%.1f)*f(%.1f)=%.20f\n',-0.5,1.1,a*b);
fclose(file);

f (-0.5) f(1.1)--0.65297430720306171000

Kindly revert for aany queries

Thanks.
