... 1 + sqrt(1 + 4 t^2 y(t)) · y'(x) = (1-x cos(y(x))) cot(y(x)). Chini-Type Equations. Solve a Riccati equation step by step: x^2 v'(x) + 2 x v(x) = x^4 v(x)^2 + 4. ) 1+tan² x = sec² x. 9.) 1+ cot² x = csc² x sin² x. 2 so that so that tan² x = sec² x - 1 cot2x = csc² x - 1. 10.) Jo. 1 ... csc x dx. = ln csc x x- cot x + C. 1. cos (x) = 1 / sec (x). The cosine of ex equals one divided by the secant of ex. tan (x) = 1 / cot (x). The tangent of ex equals one divided by the cotangent of ... cot x = 1/tan x; sec x = 1/cos x; cosec x = 1/sin x. Reciprocal Identities ... Dec 16, 2014 ...
