Question

2 sin 30° tan^2 60°-3cos^2 60° sec^2 30°
Plz answer fastt​

Answer 1

Answer:

2 is the answer

Step-by-step explanation:

firstly put values then solve it and cancel out them

at last yo will get 2

Answer 2

We know that sin (30°) = 1/2 tan (60°) = √3 cos(60°) = 1/2 sec(30°) = 2/√3

Now putting the values;

$= 2 \times ( \frac{1}{2} ) {}^{2} \times (\sqrt{3} ) - (3 \times (\frac{1}{2} ) {}^{2} \times ( \frac{2}{ \sqrt{3} } ) {}^{2} )$

$= 2 \times \frac{1}{4} \times (\sqrt{3} ) - (3 \times \frac{1}{4} \times \frac{4}{3} )$

$= \frac{ \sqrt{3} }{2} - 1$

$= \frac{ \sqrt{3} - 2}{2}$
