Taylor series determining the values and errors

Im writing a script to solve

F(x)=exp(x) focused at Xo=3 and f(5)

F(x)=sin(x) focused at Xo = 30 degress and f(157) degrees

and on each series i should get the error by subtracting n=10 from each series

here is my code and my handwritten solution, please explain to me how taylor is properly coded into matlab

syms x

f1=exp(x);
f2=sin(x);
T1=taylor(f1,'Order',5);
T2=taylor(f2,'Order',157);

diff1=taylor(f1,'Order',10);
diff2=taylor(f2,'Order',10);

errors1 = diff1-T1;
errors2 = diff2-T2;

disp(T1)
disp(T2)

You need to substitute the value of x. Read about subs, double. If T1 is your Taylor series

x = 5 ; 
val = double(subs(T1,5)) ;

For sin when you substitute the value, substitute them in radians. Convert degrees to radians.
