expand 4(1-sin^2(x))

Solution

expand

4 (1 - sin^{2} (x))

Solution

4 cos^{2} (x)

Solution steps

4 (1 - sin^{2} (x))

Apply the distributive law:

a (b - c) = ab - a c

4 (1 - sin^{2} (x)) = 4 \cdot 1 - 4 sin^{2} (x)

= 4 \cdot 1 - 4 sin^{2} (x)

Simplify

4 \cdot 1 - 4 sin^{2} (x) : 4 cos^{2} (x)

= 4 cos^{2} (x)
