(HackerRank) Write a Modular C Programming code to solve Sine Series, Sin x is a series of sin function of trigonometry; it can expand up to an infinite number of term
Sin x is a series of sin function of trigonometry; it can expand up to infinite number of term. Through this series, we can find out value of sin x at any radian value of sin x graph.
Sin(x) Series:
Steps:
First the computer reads the value of x and number of terms from the user.
Convert x to radian value x=x*(3.1415/180)
Then the value of sin(x) is calculated.
Finally the value of sin(x) is printed.
Input Format
Two input values seperated by white space.
first number is degree.
second numbe is number of terms in series.
Constraints
0 <= degree < 360
1<= terms < 100
Output Format
computed sine series answer.
Sample Input 0
45 5
Sample Output 0
Sine value of 45.000 is: 0.707
Sample Input 1
120 0
Sample Output 1
Invalid input.
Sample Input 2
270 35
Sample Output 2
Sine value of 270.000 is: -1.000Refer : C Programming HackerRank all solutions for Loops | Arrays | strings
