Note #theta) is an acute angle. Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Substitute these values in cos 2pi = cos 2 π - sin 2 π, we have cos 2pi = (-1) 2 - 0 = 1.142 in radian form or 180 degrees since 2pi = 360 degrees. Use the form to find the variables used to find the amplitude, period, phase shift, and vertical shift. Geometrically, these are identities involving certain functions of one or more angles. how do i plot sin(2pi*3t) * sin(2pi*15t).
