Question 7 | 18 points Establish each identity below. Make sure to use the method displayed in class, including stating the reasons for each step of your simplifying. A. (a sin q + b cos ()2 + (a cos q - b sin ()2 = a2 + 62 tan u + tan v B. tan u tan V = cot u + cot v C. 2 log |sin 0| = log |1 + cos 0| + log |1 - cos 0 | Question 8 | 9 points Establish the following identity. Make sure to use the method displayed in class, including stating the reasons for each step of your simplifying. sin 3x sin X cos x = 4 cos X - sec x Hint 1: Write sin 3x as sin(x + 2x) and apply a sum formula. Hint 2: The double angle formula cos(2x) = 2cos2x - 1 will be helpful, as will the double angle formula for sine
