expand sqrt((x+Δx)^2+1)

expand

(x + Δ x)^{2} + 1

x^{2} + 2Δ x^{2} + Δ^{2} x^{2} + 1

Solution steps

(x + Δ x)^{2} + 1

Expand

(x + Δ x)^{2} + 1 : x^{2} + 2Δ x^{2} + Δ^{2} x^{2} + 1

= x^{2} + 2Δ x^{2} + Δ^{2} x^{2} + 1

(3 + 7) (2 + 6)

\frac{5 ( s + 2 ) ( s + 0.1 )}{( s + 10 ) ( s + 0.01 )}

(x + 2 y - 1) d x + 3 (x + 2 y) d y

1 - (\frac{1}{2}) - (\frac{3}{92}) \cdot (9 (1.6) - \frac{1. 6 ^{3}}{3})

(- 2 + 4 i)^{6}
