Question

x=sec theta+tan theta and y=sec theta-tan theta then
(1)xy =1
(2)x square +y square=1
(3)x square +1=y
(4)x+y/xy=1

Answer 1

Answer:

x = sec teta + tan teta

y = sec teta - tan teta

_________________________

xy = 1

(1) xy = 1 is correct

Answer 2

Step-by-step explanation:

X = Sec theta + tan theta

Y = Sec theta - tan theta

__________________________

XY = 1

• Option (1) is correct
