Question

If P= Seco+tan o, so the value
p2-1/p2+1 is

​

Answer 1

Answer:

not known

Step-by-step explanation:

p=seco +tano

p²-1/p²+1

(p-1)(p+1)/(p+1)(p+1)..............i

putting the value of p in (i)

(sec +tan-1)(sec+tan+1)/(sec+tan+1)(sec+tan+1)

(sec+tan-1)/(sec+tan+1)

i just try you can set it
