I totally get where you’re coming from – trigonometric functions can be tricky at first, but once you start seeing the patterns, it gets a lot easier. So, sine, cosine, and tangent all relate to the angles and sides of a right triangle. For example, sine is the ratio of the opposite side to the hypotenuse, cosine is the adjacent side to the hypotenuse, and tangent is the ratio of the opposite to the adjacent side. Each one is useful in different situations depending on what you know about the triangle and what you need to find. To apply these in problems, just identify the sides of the triangle you have and which angle you’re working with. Also, if you're looking for some extra help with these concepts or need some clear examples, I found a site that offers
dissertation help online, and they sometimes have resources on topics like this!
