Accepted Answer

Hello, everyone. We are asked to determine the value of the given trigonometric circular function. With the help of a calculator. We want to round the answer to four decimal places. We are given the K can of negative 11.8637. Our answer choices are a 0.6463 B negative 0.6463 C 1.5474 D negative 1.5474. First, before I do anything else, I recognize that the angle measure here is in radiance. So I need to make sure my calculator is in radiant mode. If it's not, you will get a completely different answer. Next. Looking at my calculator, I see there is no KC can't button. So to find the coi can of negative 11.8637 I need to recall that Koi Can't is the same as one divided by the sign of that angle. So we're gonna do one divided by the sign of negative 11 point 8637. So I'm going to type this into my calculator just like that one divided by the sign of negative 11.8637. And when I do, I get approximately 1.5473697. Since the problem asks us to round four decimal places, I'm gonna round this to 1.5474. And that would be our value 1.5474 which is answer choice C have a nice day.
