If \[3({ cot }^{ 2 }\theta – { cos }^{ 2 }\theta )={ cos }^{ 2 }\theta, 0°<\theta <90°\] then the value of  \[({ tan }^{ 2 }\theta +{ cosec }^{ 2 }\theta +{ sin}^{ 2 }\theta)\] is ?

यदि \[3({ cot }^{ 2 }\theta – { cos }^{ 2 }\theta )={ cos }^{ 2 }\theta, 0°<\theta <90°\] है, तो \[({ tan }^{ 2 }\theta +{ cosec }^{ 2 }\theta +{ sin}^{ 2 }\theta)\] का मान है?
