expand e^x*(1-cos(y))

expand

e^{x} \cdot (1 - cos (y))

e^{x} - e^{x} cos (y)

Solution steps

e^{x} (1 - cos (y))

Apply the distributive law:

a (b - c) = ab - a c

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

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

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

Multiply:

1 \cdot e^{x} = e^{x}

= e^{x} - e^{x} cos (y)

cos^{2} (x) (2 + tan^{2} (x)) - 1

(e^{z}) \circ (z^{4} + i z^{2} + (3 - i))

\frac{2 ( 33 - 417 )}{3}

\frac{x ^{5} + 34.5 x ^{4} + 64 x ^{3} + 54}{x ^{4} ( x - 1.5 ) ^{2}}

\frac{( a - b )}{a b - b a}
