Jun 4, 2017 · Take the logarithm of y and find the limit by applying L'Hopital's rule twice. lim_{x\\to0}(sin(2x))^(tan(3x))=1. L'Hopital's rule is about evaluating limits of functions as the …

(dy)/(dx)=3sec^2 3xcsc^2 3x We can use chain rule here. In order to differentiate a function of a function, say y, =f(g(x)), where we have to find (dy)/(dx), we need to do substitute u=g(x), …

May 24, 2018 · 5/3pi. Let, y=f(x)=tan(3/5x). We know that the principal period of tan function is pi. :. tantheta=tan(theta+pi).

Mar 6, 2018 · I know that the bottom turns to sin3x/cos3x and then i multiply the recipricol in which I get the limit as x approaches 0 (sin x7)(cos3x / sin 3x) but I don't know where to go from here :

Aug 14, 2017 · This is #tan3x#, as. #tan3x=tan(x+2x)# = #(tanx+tan2x)/(1-tanxtan2x)# = #(tanx+(2tanx)/(1-tan^2x))/(1-tanx(2tanx)/(1-tan^2x))#

Oct 26, 2017 · f'(g(x)) = -2e^(2tan(3x)+4) f'(g(x)) indicates that we need to take the derivative of f, and then plug in g(x) for x.

Jun 18, 2015 · Use the chain rule and the fact that the derivative of the tangent function is the square of the secant function. I recommend memorizing this: d/dx(tanx) =sec^2 x Applying the …

STEP Maths I, II, III 1988 solutions; Mat 2k24; X coordinate of stationary point- y=e²*sin(3x) Reverse Chain Rule ...

Jul 16, 2017 · If we consider the integer triplet #a,b,c in {3, 6, 9}#, then we can derive that #tan9xtan6xtan3x=tan9x-tan6x-tan3x# (2) If we apply the same consideration to #2,4,6# we …
