WebbThe Pythagorean Identities are based on the properties of a right triangle. cos2θ + sin2θ = 1. 1 + cot2θ = csc2θ. 1 + tan2θ = sec2θ. The even-odd identities relate the value of a trigonometric function at a given angle to the value of the function at the opposite angle. tan(− θ) = − tanθ. cot(− θ) = − cotθ. WebbThe differential equation has a family of solutions, and the initial condition determines the value of C. The family of solutions to the differential equation in Example 9.1.4 is given by y = 2e − 2t + Cet. This family of solutions is shown in Figure 9.1.2, with the particular solution y = 2e − 2t + et labeled.
