R csc(x) dx = ln|csc(x) − cot(x)| ... 0 for θ ∈ [π/4, π/2]. 2. 2. Let C be the graph of the function f(x) ... (Exact solution of ˙x = sinx) As shown in the text, ˙x = sinx has the solution t = ln|(cscx0 + cotx0)/(cscx + cotx)|, where x0 = x(0) is the initial value of x. [cot(x)] = −csc2(x) d dx. [sec(x)] = sec(x) tan(x) d dx. [csc(x)] = −csc(x) ... = 0. 4. When working with trigonometric functions it is useful to have a ... Jul 5, 2020 ... Tan x and cot x are reciprocals so they are either both positive or both negative. Either way their sum cannot be zero. So tan x + cot x = 0 has ... (sinx).0+ (cosx) - 1.
