Question

sinxsecxtanxcscx = sinx/1-sin^2x

Answer 1

When you see nonsense like this, always, always, always turn everything into sines and cosines. So for instance, if you see tanx write sinx/cosx instead.

Answer 2

yup\[sinx \times 1/cosx \times sinx/cosx \times 1/sinx\]

Answer 3

cancelling those out
\[sinx/\cos^2x\]

Answer 4

Let him do it!

Answer 5

cos^2x + sin^2x = 1
then cos^2x = 1-sin^2x

Answer 6

then you get
sinx / (1-sin^2x)

tada!

Answer 7

tada! it's magic! get someone to do your homework for you! INTERNET

Answer 8

am I make myself clear

Answer 10

@Kainui yes, will be the bestseller book

Answer 11

Sadly.

Answer 12

tanx can be return as sinx/cosx

Answer 13

secx can be written i/cosx,then we get sinx/cos^2x and cos^2x can be written as 1-sin^2xthen we sinx/1-cos^2 x
