Question

If x = tan A + sin A and y = tan A -sin A, then x² - y2 =​

Answer 1

Answer:

x=tanA+sinA

y=tanA-sinA

x^2-y^2=(x+y)(x-y)

=(tanA+sinA+tanA-sinA)(tanA+sinA-tanA+sinA)

=2tanA×2sinA

=4tanAsinA answer

Answer 2

Step-by-step explanation:

given x=tanA+sinA

y=tanA-sinA

then x²-y²

formule a²-b²=(a-b) (a+b)

x²-y²=(x-y) (x-y)

=((tanA+sinA)-(
