We can add these two kinds of solutions together to get solutions of general problems, where both the initial and boundary values are non-zero. D. DeTurck Math 241 002 2012C: Solving the heat equation 4/21 The unit circle shown on the applet below allows us to explore trig values between zero and 360 degrees. Notice that some trig values are positive and some are negative. We can now define the values of cosine and sine to be the values of a point on the circumference of the unit circle. Let P be a point on the circumference of a circle with ...

And it all starts with the unit circle, so if you are hazy on that, it would be a great place to start your review. For example, let's say that we are looking at an angle of π/3 on the unit circle. The value of sin (π/3) is ½√3 while cos (π/3) has a value of ½ The value of sin (-π/3) is -½√3 while cos (-π/3) has a value of ½Defining Sine and Cosine Functions from the Unit Circle. The sine function relates a real number t t to the y-coordinate of the point where the corresponding angle intercepts the unit circle. More precisely, the sine of an angle t t equals the y-value of the endpoint on the unit circle of an arc of length t. t. In Figure 2, the sine is equal to ...

circle in R2 (say with center 0) can be parametrized by t→ (rcost,rsint) where t∈ R. The common nature of these examples is expressed in the following definition. Definition 1.1.
