Question

0 Find the value of
2 sin ²30° tan 60 - 3 cos²60°​

Answer 1

Answer:

Step-by-step explanation:

As we know that :-

» sin30 = 1/2

» tan60 = √3

» cos60 = 1/2

» sec30 = 2/√3

________________

Now,

=> 2sin²30.tan60 - 3cos²60.sec²30

Put the all values, we get :-

=> 2(1/2)²×√3 - 3(1/2)².(2/√3)²

=> 2×1/4×√3 - 3×1/4×4/3

=> √3/2 - 1

__________[ANSWER]

Answer 2

Step-by-step explanation:

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

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

$\frac{ \sqrt{3} }{2} - \frac{3}{4}$

$\frac{2 \sqrt{3} - 3}{4}$
