Signaling the End In our study of complex numbers, we are reaching the end of a pit stop dealing with trigonometry. I ended the previous post by mentioning that the trigonometric functions are periodic in nature. I claimed that this is an important feature in the study of complex numbers. In this post, we will…

Recognizing a Limitation As we continue with our pit stop in the series on complex numbers, let us remind ourselves where we have reached. In Trigonometric Identity Crises, we looked at some trigonometric identities. This followed on the heels of Round and Round, in which we saw why a right angle is defined to have…

‘Sining’ In We are in the middle of a pit stop in the middle of our series on complex numbers. The pit stop is intended to introduce the reader to the basics of trigonometry. In the previous post, we saw why we have 360° in a circle and 90° for a right angle. We also…

A Triggered Review We have reached a remarkable junction in our journey through complex numbers. We are in the middle of a pit stop in which we are looking at some trigonometric ideas. And on the occasion of Pi day 2025, I think this post makes a lot of sense. Two weeks back, in My…

The post explores the historical origins of trigonometric terms such as sine, cosine, and tangent. It traces the name “sine” back to the Sanskrit word “jīvá,” reflecting the journey of mathematical concepts across cultures. The author emphasizes the importance of knowledge transcending borders and hints at the next topic on angle measurement.

Brief Flashback My mathematical world was thrown wide open when, in the ninth grade, my classmates and I were introduced to the study of trigonometry. Following that, when I studied at IIT – Bombay, I wrote a research paper titled The Synthesis of Coupler Curves and designed a mobile industrial robot, both projects requiring the…
