Unit Circle’s equation is x² + y² = 1 All the points on the circle contains coordinates which make the equation x² + y² = 1, true! 3.6 The hyperbolic identities Introduction The hyperbolic functions satisfy a number of identities. These allow expressions involving the hyperbolic functions to be written in different, yet equivalent forms. The Pythagorean trigonometric identity – sin^2(x) + cos^2(x) = 1 A very useful and important theorem is the pythagorean trigonometric identity.

The double angle formulas can be derived by setting A = B in the sum formulas above. For example, sin(2A) = sin(A)cos(A) + cos(A)sin(A) = 2sin(A)cos(A). It is common to see two other forms expressing cos(2A) in terms of the sine and cosine of the single angle A. sin2x π 0 = 1 2 x − 1 4 sin2x π 0 = π 2 Example Suppose we wish to find Z sin3xcos2xdx. Note that the integrand is a product of the functions sin3x and cos2x. We can use the identity 2sinAcosB = sin(A+B)+sin(A−B) to express the integrand as the sum of two sine functions. With A = 3x and B = 2x we have Z sin3xcos2xdx = 1 2 Z (sin5x +sinx sin2 (2x) sin 2 (2 x) Apply the sine double - angle identity.
