Question

If x = 2020 sec theta , y = 2020 tan theta , then x^2 - y^2 =

Answer 1

Answer:

hey there here is your answer 4080400 . dont worry i will help you out

Step-by-step explanation:

here

x = 2020 sec theta

y = 2020 tan theta

so now x^2 - y^2 =  (2020 sec theta)^2 - (2020 tan theta)^2

taking (2020)^2  in common we get

(2020)^2  ( sec^2 theta - tan^2 theta )

now as we know sec^2 theta - tan^2 theta = 1 because according to identity

1 + tan^2 theta = sec^2 theta

so your answer will be ONLY (2020)^2

= 4080400
