Cosine and sine of an angle θ are defined to be the x and y-coordinates of the point P on the unit circle with the property that the line from O to P makes and angle θ with the positve x-axis. cos(θ) ...

I want to make a sine and cosine wave in an FPGA. Now, I could use a CORDIC / NCO, but I need small. I don't need any particular frequency; I just need a sine/cosine wave. I used to have a spread ...

This approach works because sine and cosine are the building blocks of all other trigonometric functions. For example, to simplify tan θ · csc θ, convert both functions: (sin θ/cos θ) · (1 ...
