Verify that (secx/sinx)*(cotx/cscx)=cscx is an identity. (x=theta BTW)

Find secx if sinx = -4/5 and 270 < x < 360. tan^2x+1=sec^2x (-4/5)^2+1=sec^2x 16/25+1=sec^2x 1...

1. (sinx/cscx)+(cosx/secx)=1 2. (1/sinxcosx)-(cosx/sinx)=tanx 3. (1/1+cos s)=csc^2 s-csc s cot...

secx/sinx-sinx/cosx=cotx

(cosxcotx/secx+tanx)+(sinx/secx-tanx)

(1 + sinx)(secx - tanx) = cos x

How to simplify secx(sinx/tanx)?

1-(sinx tanx / 1+secx)

(secx-cosx) / (tanx-sinx) = cosecx+cotx Spent hours to solve this question but failed. Please hel...
