Question
code in matlab
The exponential function can be defined by the power series as:
80
sin(z) = Σ
(-1)*
k=0 (2k+1)!
Z
z5
2k+1
Z-
+
3!
5!
-
7!
+...
a) Using recursive function technique, write a function sinusoidal
inputs: z and k. The function will output the corresponding value.
your recursive function with z = 2 and k=3
>> sinusoidal (2,3)
(z, k) that takes 2
In your script, test
ans ==
0.9079
b) Consider that z=1. Write a script that will loop through values of k until the difference
between the series and the actual value (which is sin(1)) is less than 0.0001. The script
should then print out the built-in value of sin(1) and the series approximation to five
decimal places, and also print the value of k required for such accuracy.
