Generate and represent a sine wave in Matlab

Hi every one,

I am a newbie in Matlab, I have a question as below. Anyone can help me to do it in Matlab, or give me some guide to do it.

Generate and represent a sine wave in Matlab using the following equation:

x1(n) = A1sin(2πf1t + ϕ 1)

[KSSV]

Read about the function sin.

I read it already. But in the question, all of the number, including A1,f1,t, and ϕ 1 are unknown. I dont know how to solve it

I would say, welcome to Matlab.

You will first of all need to declare your variables

let me create a matlab script to ease the guidance,

say,

A1=10;

t=1:1:100;

f1=50;

phi=90;

x1= A1*sin(2*pi*f1*t+phi)

plot(t,x1)

then you can go on and replace my values of A1,t,f1 and phi with yours and run the script

good luck

oh thank you, I understand
