If `0^@ lt theta lt 90^@` , then find the least value of (`9 tan^2 theta + 4 cot^2 theta`).

If 0^(@) lt theta lt 90^(@) , then calculate the least value of (9 tan^(2)theta+4cot^(2)theta).

If 0 lt theta lt pi//2 then .find the least value of tan theta + cot theta

If 0 lt theta lt pi//2 then .find the least value of tan theta + cot theta

If 2 cos^(2) theta = 3 sin theta, 0^(@) lt theta lt 90^(@) , then the value of ((1)/(2) cosec^(2) theta - cot^(2) theta) is:
