Question

If x = a(sec+tane) and y = b(sec 0 - tano), then xy =
a) ab sece
b) a b'tan
c) a b
d) a'b​

Answer 1

Answer:

option d

Step-by-step explanation:

x²y²= (xy)²

=(a(secθ+tanθ)²b(secθ-tanθ)²)²

=(ab(secθ+tanθ)(secθ+tanθ)(secθ-tanθ)(secθ-tanθ))²

=(ab(secθ²-tan²θ)(secθ²-tan²θ))²

=(ab)²

=a²b²
