Question

Prove Trig Equation: PLEASE HELP ME!!!

-tan^2x + sec^2x = 1

Answer 1

-tan^2x + sec^2x = 1
or, sec^2x -tan^2x = 1
or, (h/b)^2 - (p/b)^2 =1
or, h^2/b^2 - p^2/b^2 = 1
or, (h^2 - p^2)/b^2 = 1
or, b^2/b^2 =1...................proved

Answer 2

Wait so 'or' means all the different ways to prove? @goformit100

Answer 3

no it's the substitute for 'emplies that'

Answer 4

oh oops okay so thats how you would prove it?
