The Answer of Use the trigonometric substitution u = a csc θ,where 0 < θ < π/2 and a > 0 to simplify the expression $\sqrt { u ^ { 2 } - a ^ { 2 } }$ . ​
A)a tan θ
B)- a cot θ
C)a csc θ
D)a cos θ
E)a cot θ

Use the Trigonometric Substitution U = a Csc θ,Where 0 u2−a2\sqrt { u ^ { 2 } - a ^ { 2 } }u2−a2​

Use the Trigonometric Substitution U = a Csc θ,Where 0 $\sqrt { u ^ { 2 } - a ^ { 2 } }$
