When we learn about trigonometry in school, all we can think about is relations with sides of triangle and projection to the axes from unit circle as fallows.

The two right-angled triangle can seen. We will look at which has a side on x axis. We can clearly see from Pythagorean theorem that sin²(Ɵ)+cos²(Ɵ)=1.

But what manipulation of space. Well , to do that we need to see points as two separate ( cause of two dimension) real numbers. Like (x,y). Now we can do basic transformations along axes. Like if we want to move along x-axis 1 unit just…
