## The importance of mathematical toolkits for finance

For centuries, the importance of mathematics has been well-known in areas from all around the world for various practices. Mathematics was first used for trading, and is now actively used for numerous other reasons. Investors have to be well-aware of the fact that efficient trading and investing does require a comprehensive math toolkit that consists of numerous methods of calculation, such as linear algebra, probability, stochastic calculus, measure theory, mathematical logic, set theories and more.

By applying the methods outlined above in quantitative finance, investors will surely have a better time when it comes down to calculating the probability of investments yielding profit, but also when forecasting economic phenomena. Based on this, probability calculations for example, represent an essential skill for all investors, considering the fact that it is more than wise to calculate the probability of an investment turning out successful prior to making it. Not only this, but mathematical logic can also help determine whether a certain purchase or sale will benefit the investor, whereas linear algebra can showcase smarter investing trends, and also help in terms of forecasting the future value of certain stocks.

In financial practice, relevant mathematical theories are being used at all times for smarter business and investing decisions. However, investors who choose to use online services only will likely need less math skills and probably won’t have to deal with quantitative finance, as most online services already apply these formulas for better predictions, and more calculations. However, there is still a constant need of skill, regardless of how brief, alongside with an understanding of the mathematical toolkit needed for finance.

Based on everything that has been outlined so far, all people dealing with finance and investing need a basic mathematical toolkit, especially when it comes down to dealing with quantitative finance. At LucasOrchard, you’ll surely find more information about all the concepts that you may have to apply.

Complex visualization: Euler’s Identity
This is just a quick way to practice your ability to visualize in 3D, Euler’s Formula, which relates e^(ix) to the featured image, where basically the unit circle of trigonometric functions becomes a helix as the input into the function itself is mapped so f(x,y) as function of z, and we see how as we increase the Greek argument into the function, what e^(ix) is equal to remains fixed on...
