Asymptotes of Secant, Cosecant, and Cotangent. To find the x-intercepts and asymptotes of secant, cosecant, and cotangent, rewrite them in terms of sine and cosine. Notice that since secant and cosecant have 1 in the numerator and a trig function in the denominator, they can never equal zero; they do not have x-intercepts. The vertical asymptotes of the three functions are whenever the denominators are zero.
To account for the fact that CO2 (aq) is in equilibrium with H2CO3 (aq), the first acid equilibrium is normally given by. The acid equilibrium equations can be solved to give the fraction of carbonates in a particular form. Relative H2CO3 concentration is really CO2 (aq) in equilibrium with water. CO2 enters water through interface with the atmosphere and the biological processes of organic carbon digestion and photosynthesis. Aqueous carbon dioxide, CO2 (aq), reacts with water forming carbonic acid, H2CO3 (aq).
