Given the equation s2 + c2 = 1, simplify each of the following expressions. Homework Help ✎
c2 + s2
1 − c2
1 − s2
s + c
4(1 − s2)
4 − 4s2
Rewrite the given equation in its various forms.
Substitute the appropriate expressions in the problems below.
s2 = 1 − c2
c2 = 1 − s2
This is the same as: s2 + c2
This cannot be further simplified.
Factor out a 4 first. Then substitute an expression for s2.
