Question

Cosec²60° - tan²30°​

Answer 1

Answer:

☆Ur answer is 1☆

________________________

Step-by-step explanation:

=(Cosec60°)² - (tan30°)²

=(2/√3)² - (1/√3)²

=4/3 - 1/3 => 3/3 =1

Hope that it would be helpful.....

Answer 2

Answer:

Here is the answer:

Step-by-step explanation:

cosec^2 60°-tan^2 30°

cosec60°^2-tan30°^2

(2/√3)^2-(1/√3)^2

4/3-1/3

=3/3

=1

As cosec60°=2/√3,tan30°=1/√3
