If a and b are positive quantities, `(a gt b)` find minimum positive value of `(a sectheta- b tantheta)`

If a and b are positive quantities,(a>b) find minimum positive value of (a sec theta-b tan theta)

If a and b are positive quantities such that a gt b , the minimum value of a sec theta - b tan theta is

If a and b are positive quantities such that agtb , the minimum value of a sectheta-btantheta is

If aa n db are positive quantities such that a > b , the minimum value of as e ctheta-bt a ntheta is (a) 2a b (b) sqrt(a^2-b^2) (c) a-b (d) sqrt(a^2+b^2)

Prove that minimum value of atan^(2)theta+bcot^(2)theta is 2sqrt(ab) where a and b are positive quantities . Find the minimum value of 16 tan^(2) theta+9 cot^(2)theta

Eliminate theta,if x=a sectheta y=b tantheta

find tantheta if sectheta+tantheta=x
