Question

3 tan` 60° + 4 sin2 30°- cos2 60° का मान नयत कीजिये।

Answer 1

$3\left ( 4\sqrt{3}+1 \right )/4$

Step-by-step explanation:

$3tan60^{\circ}+4sin^{2}30^{\circ}-cos^{^2}30^{\circ}$

$3\times \sqrt{3}+4\times \left ( 1/2 \right )^{2}-\left ( 1/2 \right )^{^2}$

$3\sqrt{3}+4/4-1/4$

$3\sqrt{3}+3/4$

$3\left ( 4\sqrt{3}+1 \right )/4$
