Step-by-step explanation:
Using cos ^2x+sin^2 x = 1
RHS = cos ^2x+sin^2 x = 1
Therefore,
LHS = cos ^2 x − cos ^4 x
= cos ^2 x ( 1 − cos ^2 x )
= cos ^2 x sin ^2 x
= ( 1 − sin ^2 x ) sin ^2 x
= sin ^2 x − sin ^4 x
= RHS
Answer:
3/4
Step-by-step explanation:
1/2=2/4
2/4+1/4=3/4

Answer:
5.1.
Step-by-step explanation:
5.1 = 5.1000. You would then round down to find the nearest thousandth, which is 5.1.
Hope this helps!
