Answer:sin alpha= 1- sin²alpha
Sin alpha = cos²alpha............(1)
Squaring both side,
Sin²alpha = cos⁴alpha............(2)
From (1) and (2),
Sin alpha + sin²alpha= cos²alpha+ cos ⁴ alpha.

Answer:
Step-by-step explanation:
Sin alpha -sin^2 alpha = 1
Sin alpha = 1-sin^2alpha
Sin alpha = cos ^2 alpha
Sin^2 alpha = cos ^4 alpha
