Let θ belong to (0,pi/4) and t1 =(tanθ)tanθ,t2=(tanθ)cot θ, t3=(cotθ)tanθ, t4= (cotθ)cotθ, then ​A)t1>t2>t3>t4B) t4>t3>t1>t2C) t3>t1>t2>t4D)t2>t3>t1>t4

B

In the given interval, observe the graph and the maximum and minimum values the graphs of cotθ andtanθ attain. For the given interval,tanθ increases from 0 till 1. So most of the values would be less than 1 and greather than 0. For cotθ, it would decrease from infinity to 1. Hence, cotθ will always be greater than 1 in the given interval. numbers less than 1 when raised to large power tend to diminish more. Cotθ is a big number andtanθ is very small number in comparison. Use the analogy and put the values to understand the answer.

All the best
