5.2 Sum and Difference Formulas

5.2 Sum and Difference Formulas. Objective To develop and use formulas for the trigonometric functions of a sum or difference of two angle measures. Yep, they sure are!. Ain’t they a silly bunch?. What’s the point?. For example…. sin(15) = sin(45 - 30) cos(75) = cos(30 + 45)

1.4 Trig Values of any Angle

1.4 Trig Values of any Angle. (We have already talked about this). Sort of : It turns out that all of the trig values we have been talking about can also be calculated on any circle not just a unit circle (r = 1). So the values can be found using any circle regardless of its radius. .
