Application of trignometry in real life.

If x+y+z=xyz , prove by trignometry that: (2x)/(1-x^(2))+(2y)/(1-y^(2))+(2z)/(1-z^(2))=(2x)/(1-x^(2)).(2y)/(1-y^(2)).(2z)/(1-z^(2))

Using the given pattern, find the missing numbers. 1^2+2^2+2^2=3^2 2^2+3^2+6^2=7^2 3^2+4^2+12^2=13^2 4^2+5^2+[\_?]^2=21^2 5^2+[\_?]^2+30^2=32^2 6^2+7^2+[\_?]^2=[\_?]^2=[\_?][\_?]^2

Using the given pattern,find the missing numbers: 1^(2)+2^(2)+2^(2)=3^(2)2^(2)+3^(2)+6^(2)=7^(2)3^(2)+4^(2)+12^(2)=13^(2)4^(2)+5^(2)+()^(2)=21^(2)5^(2)+()^(2)+30^(2)=31^(2)6^(2)+7^(2)+()^(2)=()^(2)

Evaluate : 2/7 times ( -2/2 ) - 2/2 times 2/2 - 2/2 times 2/7

Evaluate : 2/7 times (-2 )/2 - 2/2 times 2/2 - 2/2 times 2/7
