A civil engineer is a person who design develops, and supervises construction of physical structures and systems used by the public. Such as buildings, water supply and sewage networks, roads and railways, airports, dams, tunnels, sports stadiums, and bridges. Civil
Engineers are very important to the world and we wouldn’t be where we are today without them. Many people don’t see all of the work that is involved in their job especially the math.
Math is one of the most important things that civil engineers must know because without it nothing would work the way it was meant to work. Civil engineers must use challenging math such as linear equations, trigonometry, and customary measurement in their job every day.
First of all, a linear equation is an equation in two variables where the graph in the coordinate plane is a straight line and it is also a polynomial equation. Linear equations are a type of algebra that is used by civil engineers to design and analyze complex systems. This type of algebra is used a lot in civil engineering when engineering a structure. The engineers usually use the linear equations to design and analyze load-bearing structures like bridges. When analyzing a structure it involves a lot of writing down many equations in many unknowns. The equations used in this are usually going to be linear equations. Linear equations are usually used in analyzing structures because it’s the best way. Linear equations are so important to civil engineering because it helps them to analyze structures so that they can make the structures safe for people.

Second, Trigonometry is a branch of mathematics that deals with angles, triangles and trigonometric functions such as sine, cosine and tangent. Civil engineers use trigonometry to design bridges, to build structures and systems, and to solve scientific problems. Measurements must be made first before the engineers can start using trigonometry. Trigonometry is the study of triangles, so it is used to find the angles of a triangle when the lengths are known.
Trigonometry is also used to find the lengths of two sides when the angles and one of the side lengths are known. After all of the measurements of the structure or triangle are known the civil engineer can finally begin building and defining the scope of the project that the engineer is working on. Trigonometry is very difficult but without this skill some of the structures today wouldn’t even be standing.
Finally, customary measurement is a system of measurements that civil engineers use.
There are two types of customary measurement. The United States Customary System (USCS) and the System International (SI) are the systems of measurements that they use.
Measurements are some of the most important parts in civil engineering. Without measurements the engineers wouldn’t be able to do half of the other math operations involved in civil engineering. Such as trigonometry. The engineer must first find the measurements of certain angles before they can do the other math involved. The measurements relate to mostly all of the other math that civil engineers use and without proper measurements nothing would work according to plan and civil engineers would be out of a job.
Civil engineers must use challenging math such as linear equations, trigonometry, and customary measurement in their job every day. All of this hard work pays off in the end though
