Question

If x = 3 sec square theta _1 , y = tan square theta _2 , then x _ 3y is equal to

Answer 1

Answer:

x-3y=8

Step-by-step explanation:

Given:

x=3sec^2theta-1 and y=tan^2theta-2

put the given values in equation

×-3y= 3sec^2theta-1-3(tan^2-2)

= 3sec^2theta-1-3tan^2+6

= 3sec^2theta-3tan^2theta+6-1

= 3(sec^2theta-tan^2theta)+5

= 3(1)+5. (sec^2theta-tan^2thete=1)

= 3+5

= 8
