function handles(solving equations)

How to solve the equation e^(-0.2x)sin(x+2)=0.1 in the interval 0<x<10. Using the function fzero find the 3 solutions for this equation?

solve equation y=1+e^(-0.2x)sin(x=2) in interval 0<x<10. For the two minimum points find the x and y values at these points using function fminbnd.

Must create 2 functions for this problem and use function handles to produce both required answeres?

lost and need help

[Caprisun_]

f = @(x) exp(-0.2.*x).*sin(x+2)-.1; % Define the function.

x = 0:.01:10; % Define an x range for the plot;

plot(x,f(x))

fzero(f,1)

fzero(f,5)

fzero(f,7)

Hints:

• The equation f(x) = c is the same as f(x) - c = 0
• If you have a function named g, then @g is the function handle for g.
• e^x is written as exp(x)

whats the correct syntax to write the equations? I keep getting errors in that part.

[Walter Roberson]

My guess is that you might be omitting the (implied) multiplication between the terms, but we won't know unless you show us what you have tried.

please Can you send the answer in detail

[Walter Roberson]

 g = @(x) exp(-0.2. *x) .* sin(x+2) - 0.1

and fsolve on g
