In mathematics, we calculate the volume and surface area of a sphere. We need to learn the formulas, and we can understand how to calculate the volume and surface area of a sphere by using the formulas. The formula that produces the volume and surface area of a sphere is a bit complicated. Also, to […]
In mathematical space figures, there is a problem to calculate the volume and surface area of a pyramid or cone. Unlike prisms and cylinders, how can we calculate the volume and surface area of a solid with a sharp pointed? Compared to prisms and cylinders, the calculation of pyramids and cones is more complicated. Especially […]
In mathematics, we learn about space figures. We learn the area and volume of a three-dimensional figure, not a plane. One such field is the surface area of prisms and cylinders. How can we calculate the surface area of prisms and cylinders? When calculating the surface area of a prism or cylinder, the method of […]
In mathematics, we may calculate the length of the arc and area of a sector. How do we calculate the arc length and the sector area? When calculating the arc length and the sector area, we must understand the properties of a circle. If we can calculate the length of the circumference and the area […]
In mathematics, we study probability. Probability is so familiar in our lives and all statistics are based on probability. It is because we study probability that we can understand what the news is about. Also, experimental data in science is processed using probabilities. Whether or not it will rain in a weather forecast is also […]
In mathematics, we learn about quadratic functions. It is a quadratic function with a graph of squares, and the graph has a curve. In mathematics involving graphs, we first learn direct proportionality. A graph that makes an application of proportional is a linear function. Further development of linear functions is quadratic functions. Linear and quadratic […]
An area that must be learned in mathematics is quadratic equations. Compared to linear equations, quadratic equations are more complex to calculate. In quadratic equations, there are multiple ways to answer the question. Square roots, factorization, and quadratic formulas are the most common ways to solve quadratic equations. When solving a quadratic equation, we must […]
An area of study in mathematics is square roots. The square root allows us to represent numbers before they are squared. Square root calculations include addition and subtraction. For multiplication and division, we can just multiply the numbers in the root symbol as they are. For addition and subtraction, on the other hand, the rule […]
Fractions are frequently used in square root calculations. In the calculation of fractions, the denominator may contain the root symbol. In that case, if the root sign is still in the denominator, the answer is wrong. When calculating the square root, if the denominator contains the radical symbol, it should be removed. This process is […]
In the square root, we learn multiplication and division. Typically, in mathematics, we learn addition and subtraction first. But for square roots, multiplication and division are easier. We can just multiply the numbers in the root symbol. However, there are rules for multiplication of square roots. And few people understand why it is okay to […]
