Question

(1+cotA+secA)(1+tan-secA)=
pls answer correctly
I will make you as brainliest ​

Answer 1

Answer:

cosecA=1/sinA

secA=1/cosA

And cotA=(cosA/sinA)

tanA=(sinA/cosA)

So substituting value and taking LCM we get

(sinA+cosA-1)(cosA+sinA+1)/sinAcosA

Now (a+b)(a-b)=a^2-b^2

Step-by-step explanation:

So

((sinA+cosA)^2–1)/sinAcosA

(sin^2A+2sinAcosA+cos^2A-1)/sinAcosA

Now sin^2A+cos^2A=1 SO….

2sinAcosA/sinAcosA=2

And=2

Hope you get it :)
