i need to create a method which is called double sin(double number) and use recursive function . i use Taylor series approximation and here is the code public double factorial(int number) // this is the recurision of factorial
{
if(number==0) //0!=1
{
return 1.0;
}
return (double)number*factorial(number-1);
}
public double sin(double number) // this is the method of sin(x)
{
double sinAns=0;
double sum=0;
for(int i=1;i<=9;i=i+4)
{
sum=pow(number,i)-pow(number,(i+2))/factorial(i+2);
sinAns=sum+sinAns;
}
return sinAns;
}
when i call the method, it returns back
public double factorial(int number) // this is the recurision of factorial
{
if(number==0) //0!=1
{
{
if(number==0) //0!=1
{
return 1.0;
}
return (double)number*factorial(number-1);
}
public double sin(double number) // this is the method of sin(x)
{
double sinAns=0;
double sum=0;
for(int i=1;i<=9;i=i+4)
{
sum=pow(number,i)-pow(number,(i+2))/factorial(i+2);
sinAns=sum+sinAns;
}
return sinAns;
}
when i call the method, it returns back
public double factorial(int number) // this is the recurision of factorial
{
if(number==0) //0!=1
{
and i do not know why the reason is
我对这句话感兴趣，是不是出现的语法错误？！
应该是
and i do not know what the reason is吧
The upstairs is very good at English.haha
Up 一下
I am sorry, I don't know.
