Question

decide whether the equation is a trigonometric identity.
sin^2(x)csc^2(x)=sin^2(x)+cos^2(x)

Answer 1

What do we know that \(\cos^2(x)+\sin^2(x)=?\)

Answer 2

Answer 3

1

Answer 4

1

Answer 5

and

\[\sin^2(x)*\csc^2(x)= \sin^2(x) * \frac{1}{\sin^2(x)}=?\]

Answer 6

and \[\sin ^{2}=\frac{ 1-\cos2x }{ 2 }\]

Answer 7

what you said also equals 1 so that makes this an identity

Answer 8

thanks very much

Answer 9

@zzr0ck3r i want ask u question how proof it sin^2(x) + cos^2(x) to---> sin^2(x) csc^2(x) cuz its relation equivalent

Answer 10

?

Answer 11

u understand my question or no ?

Answer 12

I don't think so.

Answer 13

i mean u proof it from one side only

Answer 14

we showed both sides equal 1

Answer 15

you understand @dinamix
