### Sin Cos Tan table chart

hi guys i need help with this program.
i need to produce a table chart of sin cos and tan from angle 1-20 using do-while loop.
currently, i have this code but there's something wrong with the output. pls i need help thanks!

#include<iostream.h>
#include<conio.h>
#include<math.h>
int main()
{
clrscr();
int z=0;
double w,x,y;
w=sin(z);
x=cos(z);
y=tan(z);
cout<<"Angle"<<"\t"<<"Sin"<<"\t"<<"Cos"<<"\t"<<"Tan"<<endl;
do
{
cout<<z<<"\t"<<w<<"\t"<<x<<"\t"<<y<<"\t"<<endl;
z++;
}
while(z<=20);
getch();
return 0;
}

the output must be

Angle Sin Cos Tan
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20

and then the corresponding value in sin cos tan of the angles

try making `z` a float as the sin(), cos() tan() functions take their values as radians not degrees.

`float z=0;`

You will need to convert your angle (z) from degrees to radians when passing them to sin() etc..
i tried it but the output was still wrong

i change int to float z;

w=sin(z*3.14159265/180);
x=cos(z*3.14159265/180);
y=tan(z*3.14159265/180);

but the output was still

Angle Sin Cos Tan
0 0 1 0
1 0 1 0
2 0 1 0
3 0 1 0
... 0 1 0
20 0 1 0

use

z*3.14159265/180.0

otherwise you'll divide by an int (180) and get an int result again.
Output your calculated angle in radians (next to where you output degrees) as well to check.
