expand (e^4cos(v),0,-2u+1)*(0,0,1)

expand

(e^{4} cos (v), 0, - 2 u + 1) \cdot (0, 0, 1)

e^{4} (0 \cdot 0 \cdot 1,,) cos (v), 0, - 2 (0 \cdot 0 \cdot 1,,) u + 1 \cdot (0 \cdot 0 \cdot 1,,)

Solution steps

(e^{4} cos (v), 0, - 2 u + 1) (0, 0, 1)

= (0 \cdot 0 \cdot 1,,) (0 \cdot e^{4},, cos (v) - 2 u + 1)

Distribute parentheses

= (0, 0, 1) e^{4} cos (v), 0, (0, 0, 1) (- 2 u) + (0, 0, 1) \cdot 1

Apply minus-plus rules

+ (- a) = - a

= e^{4} (0 \cdot 0 \cdot 1,,) cos (v), 0, - 2 (0 \cdot 0 \cdot 1,,) u + 1 \cdot (0 \cdot 0 \cdot 1,,)

(cos (\frac{x}{2}) - sin (\frac{x}{2}))^{2}

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

x^{2} - (23 + 1) x + 23

\frac{1}{( x - 5 ) ^{4}}

\frac{s}{( s ^{2} + 4 ) ( s ^{2} + 9 )}
