Question

Help? @ganeshie8 @iambatman @waterineyes

Answer 1

Sorry, I was in the process of posting it :)

Answer 2

Can you tell me one thing??

\[\sin(-x) = ??\]

Answer 3

An Odd function has a definition:

If \(f(x)\) is an odd function, then:

\[f(-x) = -f(x)\]

Answer 4

So is it B?

Answer 5

Really??

Answer 6

May be you wear glasses but I think you can see very well without glasses.. :P

Answer 7

Still B??

Answer 8

C?

Answer 9

Yes, see the definition properly:

\[f(-x) = -f(x)\]

This is only satisfied by \(sin(x)\)..

\[\sin(-x) = -\sin(x)\]

Answer 10

thank you

Answer 11

Welcome.. :)

Answer 12

I want to tell you here itself the definition of Even Function:

If f(x) is an Even function, then:
\(f(-x) = f(x)\)

Answer 13

Can you think of any trigonometric function which follows this??

Think, you will get it..
