1. Sin^2 60 +2tan45-cos^2 30 = 3.5Sin

   Step-by-step explanation:

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

   To Find : Find the value

   Solution :

   [tex]Sin 60^{\circ}=\frac{\sqrt{3}}{2}[/tex]

   [tex]Cos 30^{\circ}=\frac{\sqrt{3}}{2}[/tex]

   [tex]Tan 45^{\circ}[/tex]

   [tex]Sin^2 60^{\circ}=(\frac{\sqrt{3}}{2})^2=\frac{3}{4}[/tex]

   [tex]Cos^2 30^{\circ}=\frac{\sqrt{3}}{2}=\frac{3}{4}[/tex]

   [tex]Tan^2 45^{\circ}[/tex]

   [tex]Sin^2 60 +2tan45-cos^2 30Sin [/tex]

   [tex]\frac{3}{4}+2(1)+\frac{3}{4} [/tex]

   [tex]Hence Sin^2 60 +2tan45-cos^2 30 = 3.5Sin[/tex]
