PLEASE ANSWER THIS QUESTION BUT DON'T SPAM .... I NEED WITH FULL SOLUTION​

Answer 1

$SinO - CosO = 0$

$(Sin²O + Cos²O) = 2SinO*CosO$

$2SinOCosO = 1$

$SinO*CosO =\frac{1}{2}$

$Sin²O*Cos²O =\frac{1}{4}$

$Now ,$

$(Sin⁴O + Cos⁴O)$

$(Sin²O + Cos²O)² - 2Sin²O*Cos²O$

$1 - 2Sin²O*Cos²O$

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

$1 - \frac{1}{2}$

$\frac{1}{2}$
