Answer 1

Answer:

Step-by-step explanation:

Answer 2

$Sin^2 60 +2tan45-cos^2 30 = 3.5$

Step-by-step explanation:

Given :$Sin^2 60 +2tan45-cos^2 30$

To Find : Find the value

Solution :

$Sin 60^{\circ}=\frac{\sqrt{3}}{2}$

$Cos 30^{\circ}=\frac{\sqrt{3}}{2}$

$Tan 45^{\circ}=1$

$Sin^2 60^{\circ}=(\frac{\sqrt{3}}{2})^2=\frac{3}{4}$

$Cos^2 30^{\circ}=\frac{\sqrt{3}}{2}=\frac{3}{4}$

$Tan^2 45^{\circ}=1$

$Sin^2 60 +2tan45-cos^2 30$

$\frac{3}{4}+2(1)+\frac{3}{4}$

$3.5$

Hence $Sin^2 60 +2tan45-cos^2 30 = 3.5$
