Can someone give me a crazy math equation that equals to 1?
网页2021年11月17日 · They never equal 1. well then your calculator is bad. sin²x + cos²x = 1 is a very fundamental identity in trigonometry. Sin (x) 2 + cos (x) 2 = 1. This is a trigonometric identity. Could also be written like sin 2 (x) + cos 2 (x). I don't know if you are joking or not, but it is 1. sin (x) 2 + cos (x) 2 is always 1.
