Question

I need help with understanding a proving trigonometric equations problem:
-tan^2 x+ sec^2 x =1

Answer 1

couldn't tell you

Answer 2

Would it be the same as sec^2 x - tan^2 x =1?

Answer 3

yes

Answer 4

You're in 7th I learned this last year but i dont remember this srry

Answer 5

\[\frac{ 1 }{ \cos ^2 }-\frac{ \sin^2 }{ \cos ^2 }\]

Answer 6

i figured it out

Answer 7

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

Answer 8

Thank you:)

Answer 9

\[1-\sin ^2=\cos ^2\]

Answer 10

\[1=\cos ^2+\]

Answer 11

sin^2

Answer 12

ok you can follow that my CPU is lagging

Answer 13

or can you

Answer 14

I'm sorry, I'm still confused. Shouldn't 1-sin^2/cos^2=1 be the final solution?
