Web"y" is taken as the equal to cos (theta) because that is what you are measuring. remember the "x" axis is actually the "theta" axis. you you are graphing where cos (theta) is when theta is at a specified value. so x-axis=theta and y-axis=cos (theta). if you were trying to find the sin (theta), this would be a different graph, then that would make … WebGiven that cos theta = - 60/61 and sin theta > 0, determine the values of the sine and cosine functions for 2theta. This problem has been solved! You'll get a detailed solution …
