Question

If Sec0+tan0=P then Sec 0=?​

Answer 1

Step-by-step explanation:

sec^2 θ- tan^2 θ= 1 [formula ]

(sec θ-tan θ) (sec θ+tan θ) = 1 [by factorising]

(sec θ-tan θ) p = 1

sec θ-tan θ = 1/p--------eq-2

sec θ+tan θ=p----------eq-1

Now, by using elimination method

sec θ =1-(p) ^2/2p

or 1/2p - p/2
