WebSep 7, 2024 · Proof Because the proofs for d dx(sinx) = cosx and d dx(cosx) = − sinx use similar techniques, we provide only the proof for d dx(sinx) = cosx. Before beginning, recall two important trigonometric limits: lim h → 0 sinh h = 1 and lim h → 0cosh − 1 h = 0. The graphs of y = sinh h and y = cosh − 1 h are shown in Figure 3.5.2.
