Once you prove that exp ′ = exp, you can recover all the basic properties of exp and hence cosh, sinh, cos, sin, including: cosh ′ = sinh. sinh ′ = cosh. cos ′ = − sin. sin ′ = cos. cos ( x + y) = cos ( x) cos ( y) − sin ( x) sin ( y). WebIt is merely two functions that are related — cofunctions. Similarly, secant and cosecant are cofunctions. The same goes with the third pair of trigonometric functions, i.e., tangent and cotangent. Now, let us try to understand what cofunction identities are and where they come from. Let us begin with an example. chips draft
