2. Find the value of all the other five trigonometric functions or solve expression

If = in then

1. Find the value of all the other five trigonometric functions

sin(x)	cos(x)	tan(x)
csc(x)	sec(x)	cot(x)

2. Solve expression

If `sin(x)=5/13` then find other trigonometry
If `cos(x)=12/13` then find other trigonometry
