What is 2sec pie csc 3pie/ 2 equal to

i know the answer is 2, i just dont know how to get it.. can someone explain the steps ..?

2 sec(π) csc(3π/2) .....and you gave the answer as 2

2 sec(π) csc(3π/2)

▬▬▬▬▬▬▬▬▬▬▬ substitute sec(π) = 1/(cos(π) and csc(3π/2) = 1/sin(3π/2)

= 2 (1/(cos(π))•(1/sin(3π/2))

▬▬▬▬▬▬▬▬▬▬▬ since cos π = -1 and sin(3π/2) = -1, then

= 2 (1/(-1)•(1/-1)

▬▬▬▬▬▬▬▬▬▬▬ simplify

= 2 ((-1)•(-1))

= 2

Hope this helps you out!
