Question

How do I eliminate x from the following system?

a*tan(x) +1 = sec(x)
b*tan(x) -1 = sec(x)

Answer 1

Why would you want to do that?

Answer 2

come on that's your answer?

Answer 3

Eliminate it and leave what?

Answer 4

the answer is a*b=1 but i dont know how to get that

Answer 5

You have
a = secx-1/tanx and
b = sec x+ 1/tan x so
ab = (sec x-1)(secx+1)/tan^2x = 1

Answer 6

Thank you, I didn't try to just let the a and b alone.
