Question

what is the Value of
C cos(90- Ө)​

Answer 1

Answer:

Sine, Cosine, and Tangent are the three primary trigonometric functions through which trigonometry formulas and trigonometry ratios are defined. In a right-angled triangle, the cosine function of an acute angle is stated as the ratio of the length of the adjacent side of a right-angle triangle and hypotenuse. Here in this article, we will discuss the value of Cos 90 degree, the law of cosine, inverse cosines, and how to derive cos 90 value using unit circle.
