Trigonometry Angles–Pi/2 — from Wolfram MathWorld
12 oct. 2023By the definition of the functions of trigonometry, the sine of pi/2 is equal to the y-coordinate of the point with polar coordinates (r,theta)= (1,pi/2), giving sin (pi/2)=1. Similarly, cos (pi/2)=0, since it is the x-coordinate of this point.

trigonometry – How to read negative radians in the interval …
2 Answers. Sorted by: 1. The interval (−π 2, π 2) ( − π 2, π 2) is the right half of the unit circle. Negative angles rotate clockwise, so this means that −π 2 − π 2 would rotate π 2 π 2 clockwise, ending up on the lower y y -axis (or as you said, where 3π 2 3 π 2 is located) . You read the interval from left to right, meaning …

eix = cos x + i sin x = cisx e i x = cos x + i sin x = c i s x. This definition can be proved by observing the Taylor expansions of both the RHS and LHS. You will find they are both identical. Letting x = π 2 x = π 2 we get this: i =eiπ 2 i = e i π 2. Then just play with the powers. ii =ei2π 2 i i = e i 2 π 2. lesoutrali bot
