How can ask user to enter values of x and n?

function y = Tsin(x,n)
%Tsin calculates the sin using Taylor formula.
%Input arguments.
%x the angle in degrees, n number of terms.
z=x*pi/180;
y=0;
for k=0:n-1
    y=y+(-1)^k*z^(2*k+1)/factorial(2*k+1);
end

How can I ask user to enter values of x and n?

If ı use input function, where ı will use this function?

Thank you..

See input() function.

x = input('Input value of x :');
n = input('Input number of series terms (n) :');
 
y = Tsin(x,n)

[Emre Can Usengul]

x = input('Input value of x :');
n = input('Input number of series terms (n) :');
function y = Tsin(x,n)
%Tsin calculates the sin using Taylor formula.
%Input arguments.
%x the angle in degrees, n number of terms.
z=x*pi/180;
y=0;
for k=0:n-1
    y=y+(-1)^k*z^(2*k+1)/factorial(2*k+1);
end

RUN

>> Tsin(x, n)

Unrecognized function or variable 'x'.

[Ameer Hamza]

Paste the code like this in the script file

x = input('Input value of x :');
n = input('Input number of series terms (n) :');
 
y = Tsin(x,n)

function y = Tsin(x,n)
%Tsin calculates the sin using Taylor formula.
%Input arguments.
%x the angle in degrees, n number of terms.
z=x*pi/180;
y=0;
for k=0:n-1
    y=y+(-1)^k*z^(2*k+1)/factorial(2*k+1);
end
end

and the press the green run button in the editor menu.

[Emre Can Usengul]

So if change the name of folder Tsin.m

Then run

Unrecognized function or variable 'x'.

[Ameer Hamza]

Emre, You first need to create the function in a file like this.

Tsin.m:

function y = Tsin(x,n)
%Tsin calculates the sin using Taylor formula.
%Input arguments.
%x the angle in degrees, n number of terms.
z=x*pi/180;
y=0;
for k=0:n-1
    y=y+(-1)^k*z^(2*k+1)/factorial(2*k+1);
end
end

save this file and close it.

Now run the following lines in command window

x = input('Input value of x :');
n = input('Input number of series terms (n) :');
 
y = Tsin(x,n)
