Webwhere e is the base of the natural logarithm, i is the imaginary unit, and cos and sin are the trigonometric functions cosine and sine respectively. This complex exponential function is sometimes denoted cis x ("cosine plus i sine"). The formula is still valid if x is a complex number, and so some authors refer to the more general complex version as Euler's … WebAug 17, 2016 · #cos(alpha+beta) = cos(alpha)cos(beta)-sin(alpha)sin(beta)# along with the fact that #cos(-alpha) = cos(alpha)# With that, we have. #cos(pi-theta) = cos(pi+( …
