Question

hey guys please answer my question and I'll mark u brainliest

Answer 1

Hey mate,

First of all let's take out LCM,

cosecx^3 + cosecx^2 - cosecx^3 + cosecx^2/cosecx^2 - 1

Adding and subtracting,

= 2*cosecx^2/cotx^2

cosecx = 1/sinx

Cotx = cosx/sinx

Plugging in the values,

= 2/sinx^2/cosx^2/sinx^2

Sinx^2 gets cancelled out,

1/cosx = secx

So plugging again,

= 2secx^2

Hope this helps you out!
