Question

Define a function named sumsin that accepts double precision variable theta, double precision variable alpha, and unsigned integer n, and returns the solution of

∑ k = 0 n sin ⁡ ( θ + k α )

as a double precision value using an iterative structure (i.e. a loop). Note the symbol for theta is θ, and the symbol for alpha is α. Only show the function definition. Do not write an entire program with a main function. Just write the definition for function sumsin.

in C

Answer 1

Ans

code:-

double sumsin(double theta,double alpha,unsigned int n){

double sum=0.0;//to store result

//sum from k=0 to n

for(unsigned int k=0;k<=n;k++){

sum=sum + sin(theta+k*alpha);

}

return sum;

}

If any doubt ask in the comments.
