1. Find the exact value of sin(−), given that sin=−4/5 and cos=12/13, with in quadrant III and in quadrant IV. 2. Find all real numbers in the interval [0,2) that satisfy the equation.
3sec^2 tan =4tan
3. Simplify the following trigonometric expressions, using identities as needed:
sin()/1−cos() + 1−cos()/sin()

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.
