expand 4(1+cos(12pit)=8cos^2(6pit))

expand

4 (1 + cos (12 π t) = 8 cos^{2} (6 π t))

4 + 4 cos (12 π t) = 8 cos^{2} (6 π t)

Solution steps

4 (1 + cos (12 π t) = 8 cos^{2} (6 π t))

= 4 (1 + 8 = cos (12 π t) cos^{2} (6 π t))

Apply the distributive law:

a (b + c) = ab + a c

a = 4, b = 1, c = cos (12 π t) = 8 cos^{2} (6 π t)

4 \cdot 1 + 4 cos (12 π t) = 8 cos^{2} (6 π t)

Expand

4 \cdot 1 + 4 cos (12 π t) : 4 + 4 cos (12 π t)

4 + 4 cos (12 π t) = 8 cos^{2} (6 π t)

5 - 8 + (- 4) - (- 3)

(e + 1) (e - 1)

3 (5 x) - 2

\frac{( x - 4 ) y}{( x - 4 ) ^{2} + y ^{2}}

(1 + 3 i) (4 + 3 i)
