Question

Let $\phi: U \rightarrow \mathbb{R}^{n+1}$ be a parameterized n-surface in $\mathbb{R}^{n+1}$ and $p \epsilon U$ then show that there exist an open set $U_{1} \subset U$ about p such that $\phi (U_{1} )$is an n-surface.

Answer 1

HEy MATE HERE IS YOUR ANSWER

Hello friends ,  

Area of parallelogram = base × height  

Given : base = (2x + 3) unit  

Height =( 2x - 3 ) unit  

Now ,  

Area = (2x +3 ) × (2x -3)

=( 4x^2 - 9 ) unit^2

Answer 2
