Graphics, Figures & Tables ⇒ Function by parts help

[MakezHD]

I'm trying to write a function by parts but when I write everything and compile a (1) appears at the right side and I don't know why. Could someone help me?

Welcome,

you are using an equation environment, which differs from a usual displayed environment in just one point: It adds the number of the current equation on the right side.

Use \[ your math here \] instead.

By the way, using the cases environment seems to be a good idea.

Code: Select all

\documentclass{article}
\usepackage{mathtools}
\usepackage{blindtext}
\begin{document}
\blindtext
\[ f(x) =
	\begin{cases}
		x^{3} + 3x^{2} + 2x + 1 & x < 0 \\
		\frac{1}{x+1} & 0 \le x
	\end{cases}
\]
\blindtext
\end{document}

Hint: Paste the code as text in your post, i can't copy from an image and typing costs quite some time.

It worked. Thanks!!

Eq(1)=> Daily average load =No. of units (kWh) generated in a day/24 hours

Eq(2)=> E=mC^2

where E=Energy
m=mass
C= velocity of light

How can I write this above two equations in this template.

Hi hafizur,

how is your question related to this topic, function by parts, cases environment with a brace?
Where is the problem? A symbol, alignment, ... ?

Better open a new topic for each of your own question. This topic here is clearly marked as solved, so I guess not many users read again here to see your new question below.

I know that but this is very important for me that's why I asked here. Thanks for your suggestion.
