How to do these programs in Java?

JUST ONE.Write an opportunity to yield triangle in addition to inverted triangle till n terms depending on user’s number of triangle that they are displayed.
TWO.Write your menu powered program in order to print caused by:

sin(x) = x- (x3)/3! + (x5)/5! – (x7)/7!……..in terms

When you guys know a better solution to atleast just one, I would be very happy:) This is the homework work!

please inform the triangle
i will be supposing
1
12
123
have user preference and retailer in n
int my partner and i, j;
for(i=1; i<=n; i++)

for(j=1; j<=i; j++)
Process.out.print(j);
Process.out.println();

remember to tell inverted triangle

2nd
is usually! factorial
int my partner and i, j, cn=1, f;
two times sin=0.0, tmp;
for(i=1; i<=n; i++)

f=1;
for(j=1; j<=cn; j++)
f=f*j;
tmp=(Math.pow(x, cn))/f;
if((i%2)==0)
sin=sin+tmp;
else
sin=sin-tmp;
cn=cn+2;

And the best way will it allow you to if another does your own homework
On earth do you ask another to complete your job while you graduate and begin their day.
