Question

If x = p seco+ p tano and y =p tano + p seco then prove that
x2-y2=p2-q2 answer plz​

Answer 1

Answer:

Step-by-step explanation:

x = p secФ+ q tanФ

y =p tanФ + q secФ

x²-y² =(p secФ+ q tanФ)²-(p tanФ + q secФ)²

=(p² sec²Ф+ q² tan²Ф+2pq secФtanФ) - ( p² tan²Ф+ q² sec²Ф+2pq secФtanФ)

=p² (sec²Ф- tan²Ф) +q²( tan²Ф- sec²Ф)

=p²*1+q²(-1)

=p²-q² =RHS
