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 formula. Webt = π 6 ± 2πk and t = 5π 6 ± 2πk. where k is an integer. How to: Given a trigonometric equation, solve using algebra. Look for a pattern that suggests an algebraic property, such as the difference of squares or a factoring opportunity. Substitute the trigonometric expression with a single variable, such as x or u.
