NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It ... The reciprocal identities are: csc(x) = 1/sin(x), sec(x) = 1/cos(x), and cot(x) = 1/tan(x). Sep 16, 2021 ... Explanation · Show that 2cos xcot x+1=cot x+2cos x can be written in the form acos x-bcos x-sin x=0 , where a and b are constants to be found. (1 - cosx). [cos(1. 2 x)]. 2. = 1. 2. (1 + cosx). Sums and differences of angles ... - x) = cot(x) tan(x + π) = tan(x) tan(x - π) = tan(x) tan(π - x) = -tan(x). The identity that needs to be verified is: The right-hand side of the identity may be simplified as follows: = cos ⁡ x sin ⁡ x + sin ⁡ x sin ⁡ x [ ∵ cos ⁡ Jun 18, 2021 ... 1−cos(x)sin(x)​−cot(x)=csc(x). 3. See answers The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x . The secant of x is 1 divided by the cosine of x: sec x = 1. xn+1/n+1 (n ≠ −1), [g(x)]n g'(x), [g(x)]n+1/n+1 (n ≠ −1). 1/x, ln x, g'(x)/g(x) ... cot x, ln sin x, cot x, ln sinh x. sin2 x, x/2 − sin 2x/4, sinh2 x, sinh 2x/4 ...
