2. Viper_Feronzie

No, sorry. The fact that it IS an identity makes it a bit difficult to verify any other way.

sure

6. tcarroll010

I can do this, hold on, @lala2

7. lala2

ok :)

$1 + \frac{ \cos ^{2}\theta }{ \sin ^{2}\theta } = \frac{ 1 }{ \sin ^{2}\theta }$$\frac{ \sin ^{2}\theta + \cos ^{2}\theta }{ \sin ^{2}\theta } = \frac{ 1 }{ \sin ^{2}\theta }$

The first equation shows the left side = right side The second equation shows the left side. What I did was show that the left side equals the right side.

oh ok!

11. tcarroll010

In other words, I showed that: 1/sin^2 = 1/sin^2

12. lala2

thats clear!

13. tcarroll010

All good now? I gotta go eat! @lala2

14. lala2
