Trigonometry in computer science

Problem Detail: What’s the use of studying trigonometry in computer science? I mean, is it essential? Does it have a specific application in computer science? Because I can’t seem to muster enough motivation for learning it.

  • Rotations: that arise in Computer Graphics and Robotics , through rotation matrices, Quaternions, etc.
  • Cordics for computing these functions on a Microprocessor / FPGA
  • Transforms in Image Compression and elsewhere , e.g. FFT computation in $O(n log n)$ time
  • Anything to do with the interface between CS and Signal Processing
  • Pretty much anywhere in navigation and tracking, e.g. anything involving a GPS, IMU,etc.
  • Somewhat indirectly in Computational Geometry (CG), in its application like in coverage & localization in wireless sensor networks.

.. to name a few! So if you want to really avoid trig functions, you should learn CG 🙂
