Environment- History


There are lots of problems producing in our environment for several years but these problems are not left alone, they are in the process of being taken care of. International agreements are also in the process concerning the environment as well.

The main points of environmental problems are the natural resources, the mass consumption, the overexploitation of resources, the pollution and global warming. The environmental problems are becoming a big deal for the planet because pollution and destruction of the natural environment are increasing tremendous.

Movements were being organized to protect nature, to put pressure on governments and to raise public awareness about environmental problems. New concepts also emerged to protect our nature such as sustainable development. This development is called the Brundtland Report. Choices have been made in order to degrade our living environment and to promote sustainable development and disadvantages, as well as economic and environmental costs, that much be considered. The life style of the people on the planet is beginning to change in order to keep out planet clean.  The reduction of pollution is currently taking place which will be an exceptional way to protect the environment.

Developing International solutions to environmental problems were taking place by the United Nations offers of a natural framework. International conferences have been organized under the leadership of the United Nations..

As it is shown, the environment is being very well taken care of by the government and by the population’s actions. This will improve the environment tremendously during the period of several years.

THE IDENTITIES! 🙂IMG-20130418-00282

Pythagorean Identities

For this chapter, witting all the identities all on a sheet of paper and keeping this paper with me when I do my work will help tremendously which I have already done. Keeping my things neat, clear and in order is what should be done in this chapter the most since there are a lot of information that will take a while to remember.

The Identities are:

1. Quotient Identities

Tan x= Sin x  / Cos x

Cot x= Cos x / Sin x

2. Reciprocal identities

Sec x = 1/ Cos x

Csc x = 1/ Sin x

Cot= 1/Tan x

3. The 3 pythagorean identities

Sin ^2 x + Cos ^2 x = 1

Tan ^2 x + 1 = Sec^2 x

1 + Cot^2 x = Csc ^2 x

4. Squared Trig notation

(Sin x) ^2 = Sin ^2 x

(Tan x) ^2 = Tan^2 = (Sin x/Cos x)^2 = Sin^2 x/ Cos ^2 x

(Cos x) ^2 = Cox^2

Cot^2 x = 1/tan^2 = Cos ^2 x / Sin ^2 x

Sec ^2 x = (1/Cos x)^2 = 1 / Cos ^2 x

Csc^2 x = (1/Sin x)^2= 1/Sin^2 x


Equivalent Trig Things

As most of the time, when learning new things, we tend to find them difficult and confusing, such as the chapter we are leaning currently. But we we learn more things about it, it gets easier and easier.

To make it more simple, I try to memorize the ratios by heart and make sense of them. I write them out, put colors and study it, this helps me since I am a visual person and helps me to comprehend what I am studying.

Last class make everything more clear to me with the practice and the team work that took place and I know I will know all these “Equivalent Trip Things” like the back of my hand soon enough! 🙂

Six trig ratios

I know about the 3 other trig ratios but but my teachers told me that I would learn them later in life, and here I am now learning about them! 😀

I don’t find them difficult, its just learning something new that is almost the same as Sin, cos and tan, I just need a little bit of memorizing such as the :


Cosencant as CSC or COSEC,

Secant as SEC


Cotangent as COT

for example,

and also the reciprocal of each trig ratios.
