We have cot 3x = cot (2x+x). ⇒(cot 2x cot x)-1cot 2x + cot x. ∴ cot 3x (cot 2x+ cot x)= (cot 2x. cot x)-1. ⇒ cot 3x . cot 2x+ cot 3x . cot x = (cot 2x . cot x) ... Dec 16, 2014 ...

Aug 30, 2015 ... 2cscx Rewrite in terms of sinx and cosx 1/(1/sinx-cosx/sinx)+1/(1/cscx+cosx/sinx) 1/((1-cosx)/sinx)+1/((1+cosx)/sinx) ... 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). Recommended video: 06: ... 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. 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) Feb 19, 2017 ... Solved: Hello Everyone. Not know to graph f(x):= e^x - (1 / {e^[x*1i]}^1i) + [1/(e^pi)]*{[tan(x)]^2 - [cot(x)]^2} ? Thanks in advance. In the computation of FPS(atan(cot(x)),x,0), REDUCE is not able to ... df(y,x,3)*(x - 1) + 3*df(y,x,2)*x + df(y,x). SimpleDE(exp(x^(1/3)),x) gives. 2.
