Question 284037: sin^2 45degrees + cos^2 30degrees
Answer by user_dude2008(1862) (Show Source): You can put this solution on YOUR website!
+\cos^2(30)=\left(\frac{\sqrt{2}}{2}\right)^2+\left(\frac{\sqrt{3}}{2}\right)^2 = \frac{2}{4}+\frac{3}{4} = \frac{2+3}{4} = \frac{5}{4})
Answer: +\cos^2(30) = \frac{5}{4})
