After this activity, students should be able to: Explain that photosynthesis is a process that plants use to convert light energy into glucose, a source of stored chemical energy for the plant. Describe photosynthesis as a set of chemical reactions in which the plant uses carbon dioxide and water to form glucose and oxygen. Weband is quite simply the partial derivative along some arbitrary function v (if i remember right it's a direction), it's then noted that if the above limit exists for every v then we call the functional δ ( u; v) the first variation and denote it as δ ( u; ⋅) its then shown later in the course that for a functional J ( u) defined as
WebBased on Equations (18)–(20), variations of μ B and C B were obtained at an interval of T = 360 s. As β B and < I BC > showed stable variations over time, μ B and C B remained constant over the specific duration of the test as shown in Figure 5A,B. Thus, μ B and C B were represented as average ± standard deviation (n = 5).
