Question

Evaluate sin ^2 30degrees *cot^2 90 degrees +4tan^2 30 degrees

Answer 1

Heya !!!



Sin30° = 1/2

Cot90° = 0


Tan30° = 1/✓3



Therefore,



( Sin²30°) × Cot²90° + 4Tan²30°




=> (1/2)² × (0)² + 4 × (1/✓3)²




=> 1/4 × 0 + 4 × 1/3




=> 0/4 + 4/3



=> 0 + 16/12



=> 16/12


=> 4/3




HOPE IT WILL HELP YOU....... :-)

Answer 2

sin²30° × cot²90° + 4 tan²30°

=> (1/2)² × (0)² + 4 (1/√3)²

=> 1/4 × 0 + 4/3

=> 0+4/3

=> 4/3 [ your answer]



I hope this will help you
