Best ResponseYou've already chosen the best response.0The standard trigonometric ratios, referring to the figure: \( sin(\theta)=opposite/hypotenuse = b/c \) \( cos(\theta)=adjacent/hypotenuse = a/c \) \( tan(\theta)=opposite/adjacent = a/c \) Draw a diagram to which you can refer when you do these exercises. They are not easy to memorize, but when you will have done some exercises, they will sit in your memory automatically. Refer to your diagram often. Do not force yourself to memorize it because it will actually slow you down when you with them later on.

Best ResponseYou've already chosen the best response.0o i just need to know how to apply the sin cos and tan ratios. Possibly the recipercals also.

Best ResponseYou've already chosen the best response.0dw:1327938324698:dw So here are the six ratios, including the reciprocals. Note that I have put the length of the hypotenuse as 1. If the hypotenuse were L, then the opposite side would be L sin(\(\theta\)) and the adjacent side would be L cos(\(\theta\)).
