See answers A function is said to be continuous if Calculation: Given: f(x) = (x + 1)cotx Taking log on both sides log (f(x)) = cot x log (x + 1) = cot x + sin x cos(x − (x/2)) cos x cos(x/2). = cos x sin x. + sin x cos x ... Since x3 −x2 = x2(x−1) is increasing, f is an increasing function. If ... The cot or cotangent function is the reciprocal of the tangent function. Mathematically, it can be represented as cot x = 1/tan x. csc(x) = −csc(x) cot(x) d dx sin-1(x) = 1. √. 1 − x2 d dx cos-1(x) = −. 1. √. 1 − x2 d dx tan-1(x) = 1. 1 + x2 d dx cot-1(x) = −. 1. 1 + x2. 10. May 4, 2020 ... sinx [1 + cos x] ... 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 ... Jan 28, 2025 ... This rule is essential for differentiating functions like the one in the question, where cot x is divided by (1 + csc x).
