expand cos(e^z)*(z-1)

expand

cos (e^{z}) \cdot (z - 1)

z cos (e^{z}) - cos (e^{z})

Solution steps

cos (e^{z}) (z - 1)

Apply the distributive law:

a (b - c) = ab - a c

a = cos (e^{z}), b = z, c = 1

= cos (e^{z}) z - cos (e^{z}) \cdot 1

= z cos (e^{z}) - 1 \cdot cos (e^{z})

Multiply:

1 \cdot cos (e^{z}) = cos (e^{z})

= z cos (e^{z}) - cos (e^{z})

π (r^{2} x - \frac{x ^{3}}{3})

x (2 x + 1 = 5)

\frac{x + 6}{( x - 7 ) ( x + 5 )}

x^{2} + (2 - 3) x - 23

\frac{x + 1}{x ^{2} ( x - 2 )}
